Distributed search for balanced energy consumption spanning trees in Wireless Sensor Networks

Sensor networks are commonly used for security and surveillance applications. As sensor nodes have limited battery power, computing, and storage resources, the energy efficient security techniques are needed.

We provide a new heuristic approach to search for balanced and small weight routing spanning trees in a network. The approach is Continue reading

Energy Efficient Virtual MIMO Communication for Wireless Sensor Networks

Virtual multiple input multiple output (MIMO) techniques are used for energy efficient communication in wireless sensor networks. We investigate virtual MIMO for fixed and variable rates. We propose energy efficient routing based on virtual MIMO. The simulation results show that virtual MIMO based routing is more energy efficient as compared to SISO (single input single output) for larger distances.


In recent years, virtual MIMO has attracted a growing interest because of its energy efficiency in large field of networks. In virtual MIMO network, a group of sensors cooperate Continue reading

Agent-based peer-to-peer layered architecture for data transfer in Wireless Sensor Networks

Recently, there has been a growing interest in the potential use of Wireless Sensor Networks (WSNs) in many applications such as smart environments, disaster management, combat field reconnaissance, and security surveillance. Therefore, to realize their potential, there is a need of an architecture that facilities the deployment of a network that is optimized in terms of energy, query and network configuration.

This paper focuses on developing agent-based peer-to-peer layered system architecture for Continue reading
