ASSESSMENT OF THE CHALLENGESAND SECURITY IN WIRELESS SENSOR NETWORKS (original) (raw)

Abstract-Today, There are growing interest to use communication services; accessible for advanced reasearch which caused creating wireless sensor networks. Network security is a major challenge. Network security is so challenging task. Considering to limited resources of sensor nodes; creating security in wireless sensor network is harder rather than other traditional networks. Considering hostile nature location; wireless media and limited nature of resources in small sensor in this networks accompany with security challenges lager than traditional networks. Due to natre of location without supervision and limitation of internal resources; the security of wireless network is a challenging task. On the other hand; due to limitation of resources; the security thechniques of typical computer network in "WSN" can't be performed. However; wireless sensor networks suffer from a lot of limitations like poer limitation; Processing capabilities; unattended operation and etc. Also, It can be expected the threat and attacks in all layers of the network protocl. The wireless sensor networks have benn determined with severity of computational limitations and temporary energy resources of operating environment. In this essay, the security challenges and kinds of attacks in the sensor networks will be evaluated, due to meet challenges, The requiered strategies are suggested
