Modified TEEN for Handling Inconsistent Cluster Size Problem in WSN

WSN is a network technology which is currently in use in many existing and latest applications. Among the major problems in Wireless Sensor Networks, Energy Conservation is of utmost importance since batteries used in the sensor devices are not replaceable. There are number of cluster based routing protocols such as LEACH, TEEN, SEP proposed which handle these issues. This paper introduces an extension to TEEN protocol, a reactive homogeneous protocol. Modified TEEN (MTEEN) handles hotspot problem and the problem of load balancing in existing WSN routing algorithms. On the basis of our simulation carried on MATLAB, it is found that the proposed algorithm outperforms LEACH and TEEN in network lifetime.
