Secure Routing in Wireless Sensor Networks:Attacks and Countermeasures



INTRODUCTION
Our focus is on routing security in wireless sensor networks. Current proposals for routing protocols in sensor networks optimize for the limited capabilities of the nodes and the application specific nature of the networks, but do not consider security.

We make five main contributions.

Abstract Recent research shows that significant energy saving can be achieved in mobility-enabled wireless sensor networks (WSNs) that visit sensor nodes and collect data from them via short-range communications. However, a major performance bottleneck of such WSNs is the significantly increased latency in data collection due to the low movement speed of mobile base stations. To address this issue, we propose a rendezvous-based data collection approach in which a subset of nodes serve as rendezvous points that buffer and aggregate data origina ....etc

Abstract
A mobile ad hoc network is a mobile, multihop wireless network that does not rely on any preexisting infrastructure. Mobile ad hoc networks are characterized by dynamic topologies due to uncontrolled node mobility, limited and variable shared wireless channel bandwidth, and wireless devices constrained by battery power. One of the key challenges in such networks is to design dynamic routing protocols that are efficient, i.e., consume less overhead. The key characteristic of an on-demand protocol is the source-initia ....etc

ABSTRACT

PROJECT DESCRIPTION:
The unreachability problem (i.e., the so-called void problem) that exists in the greedy routing algorithms has been studied for the wireless sensor networks. Some of the current research work cannot fully resolve the void problem, while there exist other schemes that can guarantee the delivery of packets with the excessive consumption of control overheads. Moreover, the hop count reduction (HCR) scheme is utilized as a short-cutting technique to reduce the routing hops by listening to the neighbor s tra ....etc

Straight Line Routing for Wireless Sensor Networks
Abstract
Sensor networks are large-scale distributed sensing networks comprised of many small sensing devices equipped with memory, processors, and short-range wireless communication radio. Instead of broadcast tbased routing protocols, in this paper we propose a novel energy-efficient routing protocol, which is called Straight Line Routing Algorithm1 (SLR), for wireless sensor networks. To achieve the routing task without broadcasting, the source host constructs the event pa ....etc
