ABRM: In-Network Aggregation Based Routing Protocol for Mobile Sensor Networks with Multiple Mobile Sinks

The recent technological advances in the field of wireless sensor networks (WSN) have expanded the range of WSN applications. In some of these applications, sensor nodes are mobile rather than static. Also, the recent advances in personal digitals assistants (PDAs) allow the existence of multiple mobile sinks to collect the sensors data. These characteristics require the design of new routing protocols to meet the existence of mobile sensors and multiple mobile sinks while taken into consideration the limited resources for sensor nodes especially energy. In-network aggregation is one of the important techniques used to save power consumption. This paper presents ABRM which is an in-network aggregation based routing protocol for mobile sensor networks with multiple mobile sinks. Compared to CCBR, ABRM yields good aggregation results in addition to a great reduction in power consumption and routing cost.
