Abstract:

Advance wireless sensor network (WSN) technology is Low- power electronics and Low-power radio frequency design has enabled the development of small, relatively inexpensive & low-power sensor technology. The important challenges in design of network are three key resource1) Energy 2) Communication bandwidth 3)coverage area . LEACH (Low Energy Adaptive Clustering Hierarchical) is a hierarchical clustering algorithm. It is more efficient than proactive n reactive protocol. LEACH  protocol have some disadvantage. To overcome disadvantage we improved LEACH protocol by using optimal path forwarding algorithm and multihop technique i.e O-LEACH protocol. O-LEACH is more efficient than LEACH protocol and it uses static deployment technique. The paper is concluded by mentioning valuable observations made from analysis of results about  AODV and LEACH and Optimal LEACH  protocols.
