Fine Assessment Regarding Wireless Sensor Network Layers, Security Issues and Security Mechanism

Abstract

Wireless Sensor Networks(WSN) is a heterogeneous system combining thousands to millions tiny, inexpensive sensor nodes with several distinguish characteristics like Energy efficiency, low cost, distributed sensing, wireless, multi hop and distributed processing. WSN application widely used in many area like Medical monitoring, Inventory management, Battlefield management, Emergency response. This survey presents finer points about WSN layers, Security issues in each layer and available Security mechanism for each layers. We thrash out the uniqueness about each layers and effort. Also give comparative study about security mechanism.
