This paper deals with an integrated MAC and Routing protocol able to manage faults occurring in Wireless Sensor Network WSN . To this end the protocol design has been inspired by the crosslayer principle to minimize both the signaling overhead an ...

In interferencerich and noisy environment wireless communication is often hampered by unreliable communication links. Recently there has been active research on cooperative communication that improves the communication reliability by having a coll ...

In this paper we consider a special case of denial of service DoS attack in wireless mesh networks WMNs known as selective forwarding attack a.k.a gray hole attacks . With such   an attack a misbehaving mesh router just forwards a subset ...

eventdriven wireless sensor networks for which events occur infrequently. In such systems most of the energy is consumed when the radios are on waiting for a packet to arrive. Sleepwake scheduling is an effective mechanism to prolong the lifetime ...

Data storage has become an important issue in sensor networks as a large amount of collected data need to be archived for future information retrieval. Storage nodes are introduced in this paper to store the data collected from the sensors in their ...

  Compromisednode and denialofservice are two key attacks in wireless sensor networks WSNs . In this paper we study routing mechanisms that circumvent bypass black holes formed by these attacks. We argue that existing multipath routing approache ...

  This paper proposes a cache consistency scheme based on a previously proposed architecture for caching database data in MANETs. The original scheme for data caching stores the queries that are submitted by requesting nodes in special nod ...

Unattended nature of wireless sensor networks leads to mobile replica node attack. An adversary can capture and compromise sensor nodes make replicas of them and then mount a variety of attacks with these replicas. These replica node attacks are d ...

The link quality variation of wireless channels has been a challenging issue in data communications until recent explicit exploration in utilizing this characteristic. The same broadcast transmission may be perceived significantly differently and u ...

Adhoc networks are becoming an effective tool for many mission critical applications such as troop coordination in a combat field situational awareness etc. These applications are   Characterized by the hostile environment that they serve in ...
