Cluster forming based on spatial information using HMAC in WSN

The wireless sensor can be considered as one of the most major technologies through using it in different application such environmental applications, military commercial health applications and agriculture applications. Due to networks may deployed open area (uncontrolled area), especially applica­tions. In situ­ations, nodes are vulnerable captured. Moreover, data/control packets inter­cepted and/or modified due transmission nature.
 Consequently, security services authentication encryption done by key manage­ment which is not trivial task. management important maintain network op­erations. proposed scheme based on spatial information with data sequence then sends message each other secure way HMAC for providing safe links between forming clusters. covers goals au­thentication node.
