ABSTRACT
Abstract:
Wireless sensor networks have unique characteristics and restricted energy efficiency performance requirements that dictate special medium access control (MAC) protocols. In this work we show that design of any MAC should mainly consider the proximal nodes near the sink since they carry the most traffic while being the most crucial for survival of the network. We provide a protocol for WSN that preserve and maintain equal energy for all nodes. Network performance is modelled using analysis and verified using numerical simulations using Matlab. The MAC protocol we propose here has several attractive features: viz. is collision-free, allows smooth degradation of network due to battery discharge, combines some multiplexing schemes such as TDMA, OFDMA, TDD and FDD, sends the messages to the base station in very short time and prolongs overall network lifetime.
