A load balanced routing protocol for mobile sensor network

Wireless Sensor Networks (WSN) have gained worldwide attention in recent years, particularly with which has facilitated the development of smart sensors. WSN consists of small nodes with sensing, computation and wireless communication capabilities. In WSN, clustering is used as an effective technique to achieve scalability, self-organization, power saving, channel access, routing etc. Lifetime of sensor nodes determines the lifetime of the network and is crucial for the sensing capability. Clustering is the key technique used to extend the lifetime of a sensor network. In this proposed method, the node next to the present cluster head is selected as the new cluster head if its energy is greater than the threshold energy. Moreover all the nodes used in this method are mobile nodes. Mobile nodes increases the scope of gathering updated information. Mobile nodes also have a chance of entering remote area where cluster head cannot reach them. In this case the nodes die. In the proposed method this problem is solved, whenever the nodes tends to move out of the cluster, the nodes generates a random angle to which it is redirected. This approach will increase the network lifetime and will provide high throughput.
