Abstract	:	This thesis introduces techniques that exploit predictable mobility of the observer(data sink) to reduce communication range, thereby saving power in wireless sensornetworks (WSNs). The movement of public transport vehicles is predictable, andsuch vehicles can act as mobile observers in wide area WSNs for applications such aspollution monitoring. To understand the gains due to mobility in single hop WSNs,data collection is modelled as a queuing process, with random arrivals representingrandomness in the spatial distribution of sensors. This queuing model aids in ana-lyzing the success in data collection and in quantifying network power consumption.A communication protocol is proposed which achieves the predicted power savings.In multihop WSNs, mobility reduces the expected number of hops from sensors tothe observer, leading to significant power savings. In addition, having dedicated highdata-rate relays near the path of the observer reduces power by orders of magnitude.........-....,....-...,..tested for theQ1 PC1 bus cardBoth these projects mere sofixare des elopment efforts tonards contributing to dlfferentaspects of Roboucs and lZ1echatronics projects m the Controls and Roboucs Group..
