This paper presents considerations of using wireless sensor networks for monitoring conditions within wind farms, taking into considerations the specific of such applications. In these scenarios, which are intended to cover a lot of ground or even operate in difficult radio environments with strong attenuation, the simple and direct communication between source and destination is not always possible,...
Data aggregation is an important issue in wireless sensor networks which gathers and routes information through a multi-hop network and processes data at intermediate nodes. This paper considers how to construct data aggregation tree in wireless sensor network where there are several source nodes and a single sink. Ant Colony Optimization algorithm is an effective distributed approach. It has been...
How to get high efficient data routing for the limited energy resource networks is an important problem in the study of the wireless sensor networks. An improved routing algorithm for data aggregation based on ant colony algorithm (IACAR) is presented. The ant colony system provides a natural and intrinsic way of exploring search space in determining data aggregation. Every ant will explore all possible...
Data aggregation is an important area of wireless sensor networks. The importance of efficient data aggregation in wireless sensor networks is due to the fact of the networks which are volatile and ad hoc in nature. Problems associated include efficient energy consumption and routing techniques. Zone Efficient Localized Data Aggregation (Zelda) Algorithm has been proposed. This algorithm employs the...
In sensor networks, both energy and bandwidth are scarce resources. In the past, many energy efficient routing algorithms have been devised in order to maximize network lifetime, in which wireless link bandwidth has been optimistically assumed to be sufficient. This article shows that ignoring the bandwidth constraint can lead to infeasible routing solutions. As energy constraint affects how data...
