Area based routing protocol for mobile wireless sensor networks

Abstract

Certain applications including military, habitat monitoring, futuristic IoT, etc., require routing which needs to be done via mobile nodes with random mobility. This paper presents an energy efficient, area based routing protocol for mobile Wireless Sensor Networks (WSN). The proposed approach uses the relative positions of the source and sink to form an active region for routing. Mobile nodes in the network use a sleep-wakeup pattern to conserve energy. The mobility vector information such as current location, direction and speed, along with the node's residual energy is used to select a neighbour that can provide maximum connection retention time. Mobility vector information is also used to wake-up mobile nodes which are in the active region. The proposed approach is simulated and compared against other similar routing protocols.
