摘要：Internet of Things (IoTs) is one the substantial development that has been observed in computing paradigms in the recent years. Around 30 billion smart devices are connected to IoTs and it will be doubled by 2025. Mobile Wireless Sensor Networks makes the implementation of IoTs easier. They are extensively employed in many real-life applications like monitoring of environmental changes, disasters prediction, health care etc. As the sensor nodes are with limited energy so the efficient consumption of energy is very important for the lifetime of the network. e.g., in military surveillance application, they will be deployed in the areas where it is difficult to recharge the batteries and we need longer lifetime to watch the activities of enemies. Base station (BS) positioning is considered an effective method to improve the performance of MWSNs. The goal of this research is to minimize total energy Consumption and to prolong lifetime of a MWSN by optimizing the position of the base station in different mobility models. Location of BS is optimized by using the average values of nodes location. Our findings suggest that deployment of multiple, mobile base stations increases the network lifetime. MATLAB simulations for different mobility models with different field sizes and number of nodes are performed. The rate of energy consumption with static sensor nodes and mobile sensor nodes is also compared.
