Routing in ad-hoc networks can consume considerable amount of battery power. However, as the nodes in these networks have limited power, routing is very much energy-constrained. Continuous drainage of energy degrades battery performance as well. If a battery is allowed to intermittently remain in an idle state, it recovers some of its lost charge due to the charge recovery effect, which, in turn,...
Wireless sensor networks suffer from the problems of congestion, which lead to packet loss and excessive energy consumption. In this paper, we address both node-level and link-level congestion and propose a new routing protocol namely ant based routing with congestion control (ARCC), for wireless sensor networks, which takes into account the congestion of the network at a given instance and proposes...
In wireless sensor networks (WSNs), message security is an important concern. The protection of integrity and confidentiality of information and the protection from unauthorized access are important issues. However, due to factors such as resource limitations, absence of centralized access points, open wireless medium and small size of the sensor nodes, the implementation of security in WSNs is a...
