“…Their main advantages with respect to wireless direct transmission between source and destination are, on the one hand, the increase of coverage and battery life and, on the other hand, the reduction in the interference level. In spite of the increasing interest on MHWN, specially with the development of the cooperative or collaborative wireless networks [3], [4], the inherent complexity of these communication systems makes it very difficult to evaluate their performance in a general framework [5], [6]. In fact, to the best of our knowledge, the theoretical comparison of the end-to-end Average Bit Error Rate (ABER) between the Amplify-and-Forward (AAF) approach (analog relaying) [7], [8] and the Decodeand-Forward (DAF) strategy (digital relaying) [9]- [11] has just been exactly solved for the particular case of routes with two consecutive hops [12].…”

This paper addresses the problem of finding an analytical expression for the end-to-end Average Bit Error Rate (ABER) in multihop Decode-and-Forward (DAF) routes within the context of wireless networks. We provide an analytical recursive expression for the most generic case of any number of hops and any single-hop ABER for every hop in the route. Then, we solve the recursive relationship in two scenarios to obtain simple expressions for the end-to-end ABER, namely: (a) The simplest case, where all the relay channels have identical statistical behaviour; (b) The most general case, where every relay channel has a different statistical behaviour. Along with the theoretical proofs, we test our results against simulations. We then use the previous results to obtain closed analytical expressions for the end-to-end ABER considering DAF relays over Nakagami-fading channels and with various modulation schemes. We compare these results with the corresponding expressions for Amplify-and-Forward (AAF) and, after corroborating the theoretical results with simulations, we conclude that DAF strategy is more advantageous than the AAF over Nakagami-fading channels as both the number of relays and-index increase.

IEEE 802.11p/1609-based vehicular networks utilize a multichannel architecture to support vehicle-to-vehicle and vehicle-toinfrastructure communications. In the multi-channel architecture, the available channels in the 5 GHz spectrum are divided into one control channel (CCH) and multiple service channels (SCHs). Multiple SCHs are defined for nonsafety data transfer, while the CCH is used to broadcast safety messages called beacons and control messages (i.e., service advertisement messages). According to the channel coordination scheme, a radio interface alternately switches between the CCH and a specific SCH. The intervals during which a radio interface stays tuned to the CCH and SCH are called CCH and SCH intervals, respectively. Both intervals are set to a fixed value (i.e., 50 ms) in the standard. However, since the fixed-length intervals cannot be effective for dynamically changing traffic load, some dynamic interval division protocols have been recently proposed to support the dynamic adjustment of the CCH/SCH intervals for improving channel utilization. In this paper, we therefore provide a survey of dynamic interval division protocols for VANETs, discuss the advantages and disadvantages of them, and define some open issues and possible directions of future research.

Redesigning of traditional TCP has been one of the preferred choices among researchers to make it compatible for MANETs. Redesigns of traditional TCP, developed in the past are not more suitable due highly unpredictable environment of MANETs. Therefore, in this paper we have proposed Dynamic Ad Hoc Transport Control Protocol (D-ATP) for MANETs. D-ATP has four main concepts, improved feedback parameter estimation, mobility and life time based path selection, memory aware congestion control, and cooperative reliability enforcement. The highly dynamic networks environment of MANETs has been predicted using the information received from intermediate nodes. D-ATP has been simulated in ns-2. Traditional TCP, TCP-ELFN and ATP have been used for comparative analysis. The result analysis shows that the D-ATP outperforms all the considered protocols in terms of throughput and end-to end delay in realistic environment.
