In this paper, we propose a distributed hierarchical intrusion detection system, for ad hoc wireless networks, based on a power level metric for potential ad hoc hosts, which is used to determine the duration for which a particular node can support a network monitoring node. We propose an iterative power-aware, power-optimal solution to identifying nodes for distributed agent-based intrusion de...

VANETs (Vehicular Ad hoc Networks) are highly mobile wireless ad hoc networks and will play an important role in public safety communications and commercial applications. Routing of data in VANETs is a challenging task due to rapidly changing topology and high speed mobility of vehicles. Conventional routing protocols in MANETs (Mobile Ad hoc Networks) are unable to fully address the unique cha...

A mobile ad-hoc network (MANET) is a collection of mobile nodes which communicate over radio. These kind of networks are very flexible, thus they do not require any existing infrastructure or central administration. Therefore, mobile ad-hoc networks are suitable for temporary communication links. The biggest challenge in this kind of networks is to find a path between the communication end poin...

Mobile Ad-Hoc networks are self-configuring and self-organizing multi-hop wireless networks. They do not have any fixed infrastructure or centralized management. Due to this, the ad hoc networks are vulnerable to attacks. The routing protocol for MANET considered in this paper is AODV(Ad hoc On-demand Distance Vector Routing Protocol). Blackhole and Wormhole nodes are malicious nodes which degr...

Sensor Networks [6, 5] consist of a large number of low-cost low-power devices, each with sufficient hardware to monitor one or more variables and send and receive the readings for these variables to other devices. Wireless sensor networks are becoming a powerful tool for monitoring a range of diverse situations [3, 8]. While the devices themselves are mostly still in the prototype stage [7] th...

Solving consensus in wireless ad hoc networks has started to be addressed in several papers. Most of these papers adopt system models developed for wired networks. These models are focused towards node failures while ignoring link failures, and thus are poorly suited for wireless ad hoc networks. The HO model, which was proposed recently, does not have this drawback. The paper shows that an exi...
