Recently, wireless sensor networks are more and more used in smart building applications, due to their capability to collect data on all phenomena that happens in the building. The most important problem related to this kind of networks, is the limited lifetime of nodes, caused by their finite embedded source of energy (batteries). In order to reduce the impact of this problem, proper node model must...
Research in the field of wireless sensor networks, one of the key technologies for the success of ubiquitous computing, has mainly been focusing on the issue of energy efficiency. We propose a new MAC protocol for reducing the energy consumption. So for this Analytical model is devised in which Duty is varied according to the Traffic flow at Queue. The proposed MAC protocol solves the energy inefficiency...
In the Wireless Sensor Networks (WSNs) with randomly distributed sensor nodes, scarce and stationary sink nodes, the articulation nodes and critical regions which connect different regions are ubiquitous. The advanced invalidation of these nodes and regions will bring on “Sensor Island” and “energy hole” as traditional energy-saving strategy can hardly solve energy consumption imbalance problem, which...
In order to compare the energy efficiency of data dissemination algorithms for wireless sensor networks, we use different performance evaluation techniques. It includes either the simulation of protocol in a simulator or analysis based on an analytical model. In this article, we propose an analytical energy consumption model for grid based data gathering schemes in WSN. The purpose of this article...
