In this work we design a virtual backbone to provide energy-efficient communication in Wireless Sensor Networks (WSNs). WSNs need virtual backbones to support in-network data transmission. In scenarios where there is no spatial redundancy (such as a sensor network in a petroleum installation), Connected Dominating Set (CDS)-based algorithms can be useful for hierarchical network management. We construct...
We use a genetic algorithm (GA) to create energy efficient clusters for routing in wireless sensor networks. The simulation results show that the proposed intelligent hierarchical clustering technique is more energy efficient than a few existing cluster-based routing protocols. Further, the gradual energy depletion in sensor nodes is also investigated
Within the field of wireless sensor networks, one problem area is the limited energy supplies of the sensor nodes. In most situations, it is infeasible to replace the energy supply in each individual node. Thus it becomes important to minimize the energy expenditure of the sensor nodes, to get the maximum performance possible. There have been numerous algorithms to find the data routing schedule that...
With the advancement of micro-sensor and radio technology, wireless sensor networks are deployed in various applications. In a continuous monitoring application, sensors gather information and transmit the sensed data to base station in a periodic manner. In each data gathering round, a node generates a data packet and transmits the packet to base station, or any other node; the data packets received...
Wireless sensor networks (WSNs) enable pervasive, ubiquitous, and seamless communication with the physical world. This paper presents P2P multi-agent data transfer and aggregation system architecture in WSNs. The architecture includes four types of agents: interface, query, routing, and data acquisition agents. The interface agent interacts with the users to fulfil their interests. The routing agent...
Common applications of sensor networks include continuous monitoring where sensors are deployed over a region and the sensed data are gathered at a distant base station periodically. In each round of data gathering, our MITECRO protocol minimizes the total energy consumption of the sensor network. This may however unbalance energy consumption over all sensor nodes. As a result, few nodes may die earlier...
In this paper we present the simulation-based performance evaluation and tuning of data dissemination in wireless sensor networks. The simulation uses directed diffusion protocol for query and data dissemination. The implementation is done in Java using eclipse. The simulation includes four phases: interest propagation, gradient establishment, data propagation, and reinforcement of path establishment...
