This work details a new class of energy efficient and delay bounded data gathering framework viz. generalized intra cluster chaining (GICC) framework for large scale wireless sensor network. The framework extracts the advantages of both purely cluster based and purely chain based data gathering schemes for wireless sensor network without compromising with their drawbacks. Detailed analysis and simulation...
Data transmission is the most important issue in wireless sensor network (WSN). The energy consumption and latency are the key factors of data transmission. To optimize these factors, a noble data aggregation algorithm is proposed in this paper. The proposed algorithm is originated from LEACH, and energy efficiency and latency is considered as the researching parameters. The overlap of detect regions...
This paper proposes a smart channel assignment scheme (S-CAS) for wireless sensor networks. S-CAS performs statistical analysis of load pattern of the individual cluster and adjusts channel assignment dynamically as per requirement generated by the current traffic load. It follows a static schedule during infrastructure establishment based on initial traffic conditions and previous history and later,...
It is important to gather sensed information with an energy efficient method in sensor networks. Although data collection may save energy and improve information accuracy, it must get this at the cost of decreasing other performances, such as the delay increment. This paper proposes a Chain-based Fast Data Aggregation Algorithm Based on Suppositional Cells (CFDASC) to solve this problem. In this algorithm,...
