Dynamic Safe Transmit Power MAC protocol in Wireless Adhoc MAC protocol

Adhoc Wireless network´s performance is always measured by the number of packets successfully transmitted corresponding to power consumption of the nodes. This indirectly quantifies the battery´s life. In multihop wireless networks, every node acts as intermediate node to forward packets to other nodes. The overall network connectivity depends on the battery life. As soon as one node dies the topology of the network changes. The standard protocol IEEE 802.11 DCF MAC protocol is designed to allow transfer of packets between two neighboring nodes through the wireless media. But it consumes lot of energy, and is also unable to avoid the hidden node problem completely, thereby leading to numerous packet collisions. Researchers have proposed many MAC protocols to resolve this problem, but these schemes degrade network throughput as well as bring unfairness to the network in order to reduce power consumption. Our protocol uses the concept of Bounded Wait State to reduce power consumption and at the same time improve the fairness in the network. Through simulations we have shown that our proposed protocol shows better performance.
