A efficient key strategy for prolonging network lifetime in wireless network

This paper provides on introduction on key strategy for wireless sensor network. Many key Strategy are focus on proposed pair wise based on key strategy technique. Key management Mechanism Provide a security over a Wireless sensor network. Many Scheme are focus on proposing new pair wise based key management strategy. The key management mechanism combines trusted-server and key pre-distribution scheme which meets the security requirement of WSN. Some features of key management strategy we need a lot of energy to communicate a node with each other and increase a network size over a network through a insert a new node. Many Scheme provide a various protocol over a network. The key management Scheme contain a static and dynamic key management Strategy. We use a particular Protocol to select and analysis a accurate performance of sensor network. We use a AODV (ADHOC on demand distance vector routing protocol) Protocol use a network model. AODV Protocol basically use a network layer.
