Enhancing the lifetime of Network in MANET by Using Sleep Mode MAC Protocol Design

Ultimate aim of authors is to implement a high energy efficient data transmission protocol for Mobile Adhoc Networks (MANET) which prolongs the life time of network in a significant way. MANET devices mainly depend on a limited battery power supply to maintain the network with low power consumption techniques by utilizing the available protocol algorithms with enhanced transmission coverage range of relay nodes. Even though cooperative communication protocol method improves the transmission range of intermediate relay nodes with less power consumption, but it has not been always an effective energy efficient method as compared to direct transmission protocol concept methods. Having been studied power consumption protocol saving methods of [2] and [17], Sleep Mode Cooperative Communication power saving protocol method may be a hopeful solution in MANETs. The existing Cooperative Medium Access Control (CMAC) protocol methods only focus on throughput enhancement while neglecting to investigate the energy efficiency or network lifetime of MANETs. So, authors propose a concept of Sleep Mode Cooperative Medium Access Control protocol algorithm which will be basis on the network lifetime extension as a less traverse aspect in the related work by considering the energy consumption on both transmitter and receiver. 214 D.Vemana Chary, P.Padmanabham & Bhima Prabhakara Rao
