| Descripción: | Designing an Energy Efficient Data Transmission Protocol has a significant influence on the energy performance of Wireless Sensor Network (WSN). A set of isolated urban areas (e.g. urban parks or building blocks) covered by sensor nodes (SNs) monitoring environmental parameters (e.g., pollution, fire detection, light intensity, temperature, moisture, surveillance etc..). Mobile sinks (MSs) are fixed upon the public vehicles with fixed trajectories (e.g. buses) to collect the sensory data from WSN fields. Within the MS’s range the existing system involve either single-hop transfer of data from SNs involving in data retrieval, processing, buffering and delivering tasks. These nodes run the risk of rapid energy consumption causing decreased network lifetime and loss of network connectivity. Our proposed protocol aims at minimizing the overall network overhead and energy expenditure associated with the multihop data retrieval process while also ensuring balanced energy consumption among SNs and prolonged network lifetime. This can be achieved through building cluster structures consisted of member nodes that route their measured data to their assigned cluster head (CH) and a mobile sink deployed in sensor area collects the sensory data from cluster heads through random path. CHs performs data filtering upon raw data exploiting potential spatial-temporal data redundancy and pass the filtered data to appropriate end nodes with sufficient residual energy, located in proximity to the MS’s trajectory. Simulation results confirm the effectiveness of our approach against as well as its performance gain over alternative methods. |
