PROJECT TITLE:

Improving the Network Lifetime of MANETs through Cooperative MAC Protocol Design - 2015

ABSTRACT:

Cooperative communication, that utilizes nearby terminals to relay the overhearing information to attain the diversity gains, contains a nice potential to improve the transmitting potency in wireless networks. To house the difficult medium access interactions induced by relaying and leverage the advantages of such cooperation, an efficient Cooperative Medium Access Control (CMAC) protocol is required. In this paper, we tend to propose a completely unique cross-layer distributed energy-adaptive location-primarily based CMAC protocol, particularly DEL-CMAC, for Mobile Ad-hoc NETworks (MANETs). The design objective of DEL-CMAC is to improve the performance of the MANETs in terms of network lifetime and energy potency. A sensible energy consumption model is utilized in this paper, which takes the energy consumption on each transceiver circuitry and transmit amplifier into account. A distributed utility-primarily based best relay choice strategy is incorporated, that selects the best relay primarily based on location data and residual energy. Furthermore, with the purpose of enhancing the spatial reuse, an innovative network allocation vector setting is provided to deal with the varying transmitting power of the supply and relay terminals. We have a tendency to show that the proposed DEL-CMAC significantly prolongs the network lifetime beneath numerous circumstances even for high circuitry energy consumption cases by comprehensive simulation study.
