چکیده
In this paper, a cluster-based virtual multiple-input multiple-output (MIMO) communication scheme is proposed for energy-constrained wireless sensor networks. We investigate virtual MIMO for fixed and variable rates. We propose energy efficient routing space-time block coding (STBC) based virtual MIMO technique is incorporated into low-energy adaptive clustering hierarchy (LEACH). In addition, an analysis model based on energy consumption of the whole network The simulation results show that virtual MIMO based routing is more energy efficient .

Target Tracking Based on Virtual Grid in Wireless Sensor Networks
One of the most important and typical application of wireless sensor networks (WSNs) is target tracking. Although target tracking, can provide benefits for large-scale WSNs and organize them into clusters but tracking a moving target in cluster-based WSNs suffers a boundary problem. The main goal of this paper was to introduce an efficient and novel mobility management protocol namely Target Tr...
متن کاملAn Adaptive LEACH-based Clustering Algorithm for Wireless Sensor Networks
LEACH is the most popular clastering algorithm in Wireless Sensor Networks (WSNs). However, it has two main drawbacks, including random selection of cluster heads, and direct communication of cluster heads with the sink. This paper aims to introduce a new centralized cluster-based routing protocol named LEACH-AEC (LEACH with Adaptive Energy Consumption), which guarantees to generate balanced cl...
