Security protocols in wireless tactical sensor networks

Advances in technology led to the development of sensor networks at low cost. Sensor networks can he used in several application areas including military, health, home, environmental and space exploration. Sensor nodes have several constraints, like limited computational and energy resources that pose design issues to researchers. In tactical sensor networks security plays an important role, since these networks are deployed in hostile environments and run safety-critical applications. This paper presents security protocols used in wireless networks and considers how well these algorithms can he applied to wireless tactical sensor networks
