To select fair and balanced cluster head for cross layer protocol in wireless sensor network, a novel scheme is proposed in this paper. Because LEACH-C and its most of the variants select cluster head by considering energy and distance as a crucial parameter, it can reduce energy consumption of nodes but fail to create balanced cluster. According to the requirement of fair CH selection, we consider...
In this paper, we analyze an IEEE 802.15.4-compliant wireless sensor network, organized in clusters with fusion centers (FCs) acting as cluster heads. Sensors observe the same common binary phenomenon, decide on its status, and send their decisions to the FCs, which perform a majority fusion. FCs' decisions are then sent to an access point, where a final estimate is obtained. Data aggregation (DA)...
In wireless sensor networks (WSN's), data aggregation is used to increase energy efficiency by means of eliminating redundancy and forwarding the collected abstract data of sensor nodes toward the sink. One of the most important challenges in WSN is to keep the remaining energy of nodes high and balanced to achieve longer system lifetime. In this article we propose an energy efficient data aggregation...
A wireless sensor network consists of a large number of sensor nodes scattered in the region of the network which have limited energy and limited computational and sensing ability. Data aggregation is important in this kind of network which can make use of the energy of the sensor nodes efficiently, and reduce the traffic in network by utilizing the abilities of the nodes in local computation and...
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 has been proposed as one method for reducing energy consumption in sensor networks. One critical factor in data aggregation is routing. In this paper, we generalize the present routing schemes and find that they are all static and thus cannot change when data packets flowing to sink. To make data aggregation more efficient, we design data aggregation protocol based on dynamic routing...
