One of these applications that will be tackled in this paper is monitoring electromagnetic (EM) pollution that is mostly caused by a variety of wireless devices that we use in our daily life. This paper presents a generic algorithm that uses a WSN to monitor EM hazardous emissions and reports variation caused by four violators. Additionally it calculates the network’s lifetime and simultaneously studies the effect of random parameters and their distributions on the network. Finally the different combinations of the random parameters and the altered distributions are compared together to achieve the combination that can prolong the network’s lifetime.展开更多

In recent years, a significant amount of research has focused on improving network lifetime irrespective of the network throughput. This paper focuses on improving network throughput by using efficient coding techniques and different coding schemes without affecting the lifetime. It is shown that throughput increases with the increase of the BCH coding rate. Also, the use of multi coding is investigated. Different rates/codes are studied between sensor nodes and the network master (NM) and between the NM and the sink.展开更多
