Power consumption efficiency for wireless sensor network in MAC protocol

Abstract

The Wireless Sensor Network (WSN) has been a hot research topic which deals with remotely sensor a particular criterion or a few criteria in a given area. Due to the fact that WSN nodes are placed remotely (most of the cases), the do not have an unlimited power supply to provide energy to this node. On the other hand, they utilize a limited power source such as a battery. The limited resource has cause the WSN nodes unable to function for a given long period of time and having to be maintained more frequently especially the changing of batteries which might in turn defeat the purpose of placing it remotely. Numerous researches have been on going to improve the power efficiency in the WSN nodes by having better algorithm, protocols and so on. My focus in this proposal is to tackle the problem found in the Medium Access Control (MAC) Protocol that is the Overhearing and also the Control Packet Overhead. The Overhearing describes the nodes listening to the packets that are not destined for it. While the Control Packet Overhead talks about the Control Packets used to communicate and manage between nodes.
