A Mobile Ad hoc NETwork (MANET) is a self-organizing, temporary, infrastructure-free, multi-hop, dynamic topology wireless network that contains collection of cooperative autonomous freely roaming mobile nodes. The nodes communicate with each other by wireless radio links with no human intervention. Each mobile node functions as a specialized router to(More)
Node compromisation is a potential threat to unattended wireless sensor network applications. An attacker can launch various types of attacks. Node Compromise Detection (NCD) and revocation methods should be invoked promptly to mitigate the damage. Broadly two categories of schemes exist for the NCD, namely, Behaviour based and Attestation based. Behaviour(More)
Wireless Sensor Networks are energy-constrained and thereby require energy-efficient protocols to maximize the network lifetime. Since many sensors have closely-related readings, correlated data gathering has emerged as an efficient approach for achieving energy conservation. Hence, the objective of this work is to study the existing literature on(More)
Wireless Sensor Networks (WSN) is an ever growing field owing to their extensive variety of applications. WSN have limited battery energy, consequently, an energy efficient routing protocol is of major concern. LEACH (Low Energy Adaptive Clustering Hierarchy) is one of the fundamental clustering protocols in WSN that provides high energy efficiency. Many(More)
This paper deals with information discovery and aggregation in large scale wireless sensor networks applied for mission-critical applications like military reconnaissance. To support query processing based on the gathered information, an efficient and reliable information discovery mechanism is proposed for sensor networks. We extend the basic Comb-Needle(More)
