Sensor deployment is one of the key topics addressed in Wireless Sensor Network (WSN). This paper proposes a new deployment technique of sensor nodes for WSN called as Quasi Random Deployment (QRD). The novel approach to deploy sensor nodes in QRD fashion is to improve the energy efficiency of the WSN in order to increase the network life time and coverage. The QRD produces highly uniform coordinates...
The interconnection of mobile devices in urban environments such as shopping malls can open up a lot of vistas for collaboration and content-based services. This will require setting up of a network in an urban environment which not only provides the necessary services to the user, but also ensures that the network is energy efficient. In this paper, we propose an energy efficient dynamic routing...
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...
