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


Cooperative Communication, that utilizes nearby terminals to relay the overhearing info to attain the range gains, includes a great 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 needed. In this paper, we tend to propose a unique cross-layer distributed energy-adaptive location-based mostly CMAC protocol, particularly DEL-CMAC, for Mobile Ad-hoc NETworks (MANETs). The look objective of DEL-CMAC is to enhance the performance of the MANETs in terms of network lifetime and energy potency. A sensible energy consumption model is utilised in this paper, that takes the energy consumption on each transceiver circuitry and transmit amplifier into consideration. A distributed utility-based mostly best relay selection strategy is incorporated, that selects the best relay based on location info and residual energy. Furthermore, with the aim of enhancing the spatial reuse, an innovative network allocation vector setting is provided to house the varying transmitting power of the source and relay terminals. We have a tendency to show that the proposed DEL-CMAC significantly prolongs the network lifetime below various circumstances even for prime circuitry energy consumption cases by comprehensive simulation study.
