"Some Important Enhancing Protocol Issues for Wireless Sensor Network, A Survey"

Wireless Sensor Networks (WSNs) consist of small sensor nodes with sensing, computation, and wireless communications capabilities. Sensor nodes sense physical phenomena or collect data from an environment. Sensor nodes have inevitable impact over the network's performance; here are still limitations that WSNs suffer. The energy consumption is one of the most common problems in the wireless sensor network. Innovative techniques that improve energy efficiency to prolong the network lifetime are highly required. Clustering is an effective approach in wireless sensor networks, which can increase network lifetime. In our paper we have surveyed various enhancing clustering protocols for wireless sensor networks and compared on various parameters like, message count, node deployment, Network Lifetime, location awareness and cluster head selection process etc.
