A Combat Approach to Overcome Attacks in Different Layers of Wireless Sensor Networks

Abstract

The new era of computing is now done through wireless sensor networks. The sensor nodes though small are very powerful. A WSN consists of many distributed autonomous sensors cooperatively pass their data through the network to a main location. Each sensor network node has typically several parts-a transceiver, a microcontroller and a power source usually a battery. As it is used in most of the real time applications, the threat to data confidentiality and integrity also increases over the internet/network. Attacks at all the layers of network protocol can be expected. This paper deals with security aspects in the wireless sensor networks and probably giving the counter measures for the same.

Keywords- WSN, combatmodel, Denial of service, confidentiality and integrity.
