Abstract:
Wireless sensor networks are used for various applications. In this paper, we propose an energy efficient cluster based routing protocol along with prolonged network lifetime for WSN. In this we introduce a cluster heads, head set, for cluster based routing. Prolonged network lifetime, scalability, and load balancing are important requirement for many sensor network applications. Clustering sensor nodes is an effective technique for achieving these goals. In this work, we introduce an energy efficient clustering algorithm for sensor networks based on the LEACH protocol. This is a clustering-based protocol that minimizes energy dissipation in sensor networks. It performs self organizing and re-clustering function for every round. The primary advantage of LEACH protocol is reducing the number of communication to sink using cluster head (CH), reduce data through compression technique, it increase the lifetime of all nodes through random rotation as cluster head. The utility and functionality of a sensor network can be greatly enhanced by introducing mobility to some or all of the nodes. This will introduce few challenges like limited transmission range, broadcast nature of wireless medium, unpredictable mobility, limited bandwidth and restricted battery power. Due to the mobility of nodes in the networks it is non-trivial problem to find the range of non cluster head node from cluster head and perform the communication between nodes for a long period of time. A sensor node transmits its sensed data in its timeslot and broadcasts a joint request message to join in a new cluster which increases the unsuccessful packet delivery rate and increased control overhead(to find range of each node from cluster head), which causes more energy consumption and reduce the network lifetime. To address this problem, we propose a Group Based Energy Efficient Algorithm (GBEE), applied within clusters .It will take a fixed interval of transmission time into account in order to find range of a node in cluster to avoid unsuccessful packet transmission to nodes which are out of range from a cluster head. This saves the battery power of sensor nodes which automatically prolongs the network lifetime, forms a robust network that can respond dynamically to changing environmental conditions.
