This book was released on 1991 with total page 93 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although the issues of routing and scheduling in packet radio networks are highly interdependent, few studies have addressed their interactions. After reviewing the major issues associated with the joint study of these problems, we address both components individually. Each is formulated as a combinatorial-optimization problem, and Hopfield neural network (NN) models are developed for solving several versions of these problems. A key feature of our models is the use of the method of Lagrange multipliers, which permits the coefficients in the connection weights to vary dynamically with the evolution of the system state. Extensive software simulation results demonstrate the capability of our approach to determine good sets of routes and link activation schedules. These results also demonstrate that these problems are not separable, i.e., that a model that jointly optimizes routes and link-activation schedules is needed. Issues associated with the extension of this approach to the join routing/scheduling problem are discussed, and a preliminary description of such a model is provided.

This book was released on 2002 with total page 19 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this paper, based on coding theory concepts, new time scheduling algorithms for multihop packet radio networks are described. Each mobile host is assigned a word from an appropriate constant weight code of length n, distance d and weight w. The host can send a message at the j[superscipt th] slot provided the assigned code has a 1 in this j[superscipt th] bit. The proposed algorithms are better than the previously known algorithms in terms of minimum system throughput and/or delay bound. The algorithms also preserve other desired properties, such as topology independence, guaranteed minimum throughput, bounded maximum delay, and fair transmission policy. In the simulation, we measure the average system throughput of transmission scheduling algorithms. The simulation results show that the proposed algorithms outperform the previously known algorithms in terms of mean system throughput.

This book was released on 1993 with total page 4 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the classic transmission scheduling problem, the nodes of a Packed Radio Network (PRN) broadcast fixed-length packets over a common resource (the channel). Packet transmissions are subject to interference constraints; for example, if a node is transmitting a packet, then all adjacent (neighboring) nodes must refrain from transmission. One then adopts a slotted time model where every slot is allocated to a set of nodes which can simultaneously transmit without conflict. Thus, a node is generally belongs to one or more of these sets(called transmission sets). Our approach is based on viewing the transmission scheduling problem as a single server multiclass polling problem with simultaneous resource possession. Here, a class corresponds to a transmission set. The server corresponds to a channel operating with deterministic service times: a service time is equal to one time slot required for transmitting a packet. The scheduling problem is then equivalent to assigning the server (equivalently, each time slot) to a particular transmissions set. The simultaneous resource possession feature arises because the server is assigned to a transmission set, i.e. it can simultaneously provide service to packets from all nodes which belong to that set. The construction of the transmission set is dependent upon the topology and connectivity of the PRN and is equivalent to a graph partitioning problem. For our purposes, we assume M transmission sets have been specified. Finally, we allow for overlapping transmission sets, i.e. a node can belong to two or more difference transmission sets.

This book was released on 2006-07-06 with total page 716 pages. Available in PDF, EPUB and Kindle. Book excerpt: Following the pattern of the Internet growth in popularity, started in the early 1990s, the current unprecedented expansion of wireless technology promises to have an even greater effect on how people communicate and interact, with considerable socio-economic impact all over the world. The driving force behind this growth is the remarkable progress in component miniaturization, integration, and also devel- ments in waveforms, coding, and communication protocols. Besides established infrastructurebased wireless networks (cellular, WLAN, sat- lite) ad-hoc wireless networks emerge as a new platform for distributed applications and for personal communication in scenarios where deploying infrastructure is not feasible. In ad-hoc wireless networks, each node is capable of forwarding packets on behalf of other nodes, so that multi-hop paths provide end-to-end connectivity. The increased flexibility and mobility of ad-hoc wireless networks are favored for appli- tions in law enforcement, homeland defense and military. In a world where wireless networks become increasingly interoperable with each other and with the high-speed wired Internet, personal communication systems will transform into universal terminals with instant access to variate content and able of handle demanding tasks, such as multimedia and real-time video. With users roaming between networks, and with wide variation in wireless link quality even in a single domain, the communications terminal must continue to provide a level of Quality of Service that is acceptable to the user and conforms to a contracted Service Level Agreement.

Download or read book Conditions for Product Form Solutions in Multihop Packet Radio Network Models written by Jose M. Brazio and published by . This book was released on 1985 with total page 33 pages. Available in PDF, EPUB and Kindle. Book excerpt: Consider multihop packet radio networks operating under a general class of channel access protocols. For the purpose of throughput analysis, analytical models are considered which describe the joint activity of the transmitters in the network, under the assumptions of heavy traffic and zero propagation and processing delays. The problem addressed in this report is that of finding conditions for the existence of product form solutions for the steady-state probabilities of these models. The main result states that a necessary and sufficient conditions for a given network topology, channel access protocol, and traffic pattern, to lead to a product form solution is that the blocking between each pair of used links, as specified by the access protocol, by symmetric. This result assumes Poisson scheduling point processes associated with the links of the network. The proof is given in two steps: first, for systems where all packet length distributions are exponential, giving rise to Markovian processes; and second, for general packet length distributions (subject to the restriction of possessing a positive density almost everywhere), giving rise to Generalized Semi-Markov Processes. It is also shown that a product form solution does not exist whenever any of the scheduling point process in the network is not Poisson. In addition, it is proven that the computation of the normalization factor appearing in the expression of the product form solution is an NP-hard problem. (rh).
