Data aggregation is known as the collection of data from a set of sensors toward a sink node with routing algorithms. For that, many structured protocols used for aggregation and forwarding packets. Since, sensor nodes are less battery powered devices, its maximum energy spent for constructing certain topologies. There are number of prior works based on tree-based or cluster-based, grid based and...
In this paper, we formulate coverage requirements of the sensor network as a minimum-cost connectivity guaranteed point k-coverage problem. An improved ant colony algorithm (EasiDesign) is proposed to achieve the approximate solution to this optimization problem. We made modifications in the convergence strategy and the ant state transition rule of the general ant colony optimization. Considering...
We consider an agent-target assignment problem in an unknown environment modeled as an undirected graph. Agents incur cost or reward while traveling on the edges of this graph. Agents do not know the graph or the locations of the targets on it. However, they can obtain local information about these by local sensing and communicating with other agents within a limited range. To solve this problem,...
Wireless sensor networks (WSNs) consist of small nodes with sensing, computation, and wireless communication capabilities. Many routing, power management, and data dissemination protocols have been specifically designed for WSNs where energy awareness is an essential design issue. The focus, however, has been given to the routing protocols which might differ depending on the application and network...
The problem of computing a route for a mobile agent to local regions or specified nodes in a distributed sensor network is considered, both in a single region or multi-region cases. With all specified nodes visited, this paper formulates the route computation problem in terms of minimizing an objective function, which is directly proportional to the energy consumption and path loss. Further, we propose...
The nodes in wireless sensor networks are prone to failure due to fading energy. The wireless sensor network applications that require continuous data-supply, suffer due to energy limitation of the sensor nodes. A technique based on soft- sensing principles is employed in this paper to assure the availability of data to these applications, where there is no compromise on data acquisition due to node...
