Performance Analysis on Energy Aware MAC protocol for Wireless Sensor Network
Swati A. Joshi, Tejaswita R. Bhandari · 2011
Wireless Sensor Network has been widely used in variety of fields. However, the energy problem has been a challenge in practical applications for WSN. The radio transmission consumes lots of energy in WSN as compare to other subsystems. The MAC protocol controls the radio transmission. Medium Access Control has a significant effect on the energy consumption. In the performance evaluation of a protocol for wireless sensor network, the protocol should be tested under realistic conditions for representative data traffic models. Several techniques are available that described an energy-efficient S-MAC protocol, which is a well-known MAC protocol for WSN. The others protocols remove the defects of S-MAC. The major problem with different MAC protocols is they itself consume lots of energy while accessing channel, overhearing, and collision. Some methods reduce this by using different technology but at the cost of increased latency. The basic problem of energy utilization is ignored in the existing protocols. Each node utilizes same amount of transmission power irrespective of the distance from destination node. To solve problem and distance issue, some new research on MAC protocol is required. The ES-MAC protocol gives the enhancement to basic S-MAC protocol and removes the drawback of current S-Mac protocol.
