Abstract: In this thesis, we improve the performance of body sensor networks (BSNs) in moderate-scale deployment scenarios. Firstly, we present an improved handover scheme with movement trend awareness for BSNs. Handover initiation time is optimized to minimize the outage probability while the predicted handover rate meets the requirement. Secondly, we investigate the prevalence and severity level of inter-user interference in a realistic BSN deployment scenario in a hospital. Thirdly, we propose a lightweight and distributed inter-user interference mitigation (IIM) scheme for BSNs. The proposed scheme takes into consideration the generic property of low channel utilization in BSNs and enables affected BSNs to adaptively reschedule their transmission time or switch channels. Fourthly, we present a stochastic geometry analysis of inter-user interference in BSNs. In the analysis, we evaluate the performance of BSNs in terms of outage probability and spatial throughput. The effects of the IEEE 802.15.6 medium access control (MAC) are considered.
