Performance Evaluation of Existing Interference Mitigation Techniques under Designed Interference Environment
According to the latest report, 10% people in India die because of cardiovascular diseases. This mortality rate can be reduced by using state of art technology which can give early warning signs of such attacks. Thus, Wireless Body Area Network (WBAN) arrangements where remote patient monitoring is made possible can help in this context. Also, WBAN can reduce the cost of hospitalization and ensure comfort level of the patient. This paper is an outcome of our ongoing research to design robust Wireless body area network for remote patient health monitoring system. Our previous work confirmed that designed WBAN can be extremely useful for remote patient monitoring, however WBAN are prone to interference. Interference is a phenomenon of overlapping wireless ranges of WBANs thus there is a need to test performance of designed WBAN under interference. Interference reduces the reliability of the transmission of the data, the throughput and increases the power consumption. In WBAN vital body parameters are sensed and transmitted wirelessly to the health service provider. Any delay in transmission of the data due to interference could be dangerous for patients’ health. Thus, the efforts should be made to mitigate interference.
Thus, performance of the designed WBAN under the influence of interference is reported in this paper. For performance analysis, three parameters i.e. delay, power consumption and throughput are considered. Also, effectiveness of two existing, concurrent Interference Mitigation Techniques (IMT) is evaluated for the interference reduction for Designed WBAN. First, the designed WBAN is tested under Interference environment without mitigation technique. Later on, a performance of SCA (Smart Channel Assignment) and ITLS (Interference Aware Traffic Priority Based Linked Scheduling) interference mitigation algorithms are tested under same interference environment and comparative statements are made. Purpose of such comparative analysis is to find the scope of development of new or better IMT for designed WBAN.
