Vehicular Ad hoc Networks (VANETs) are a special type of Mobile Ad hoc Networks (MANETs), made by vehicles communicating among themselves, and by vehicles communicating to devices located in the margins of roads and highways. The main characteristic of a VANET is the high speed of network nodes - that can go up to 200 km/h -, and that impacts directly on the ability the network has to deliver data,...
In this paper we present a survey on Genetic Operators for d-MST problem with a discussion. The contribution has two parts. The first part contains the specification of the proposed operators of crossing and mutation. The new operators offer the locality, complete heredity, and are nevertheless computationally efficient. We target to generate only valid solutions without intermediate stages such detection's...
This paper presents a communication framework for cross-layer design to improve network performance in the wireless networks. The proposed communication framework consists of the following two things. First, we propose the XCP (eXtensible Cross-layer design Platform) that enables the exchange of information between different layers for performance optimization. Second, the CAR (Cross-layer approach...
We consider the optimized joint design of the physical, medium access control, and network layers to maximize the lifetime of energy constrained wireless ad hoc networks for multicast applications. In this case, using network coding at the network layer, the problem of computing maximum lifetime multipath flow is formulated as a linear optimization problem, when the transmission rates of the links...
In this paper, we consider the mobility effect with a jointly optimal design of cross-layer congestion control, routing and scheduling for ad-hoc networks. We first formulate the rate constraint and scheduling constraint. In this way, we use multi-commodity flow variables. Then formulate resource allocation in networks with fixed wireless channel and single-rate devices. Because of entrance of the...
We introduce a novel approach to routing based on the so called pairwise packet delivery ratio matrix whose entries represent the probability that a given user decodes the packet transmitted by any other user. We show that this leads naturally to a model in which routing algorithms are described by the evolution of a Markov chain enabling the definition of deliverability criteria in terms of absorbing...
