Abstract & Overview
Some wireless sensor network is traditionally is used to gather information form remote/unmanned area.Always focus on network insist on precisions data collection.Traditionally all sensor network design address challenges like coverage, lifetime and routing related issues.Due to the wide spread application of senor network, it is started using in many critical application like defence, atomic reactor, national security etc.where data security become important than other parameters.Blackhole attack is one of the attack attack which can spread the system with improper information, hence the entire system become obsolete.A trust score based blackhole attack identification can be implemented and affected nodes can be identified.Eliminating such black hole nodes from network may increase routing overhead but it always enhance throughput of network since the network carry any fruitful information.
