To avoid the negative impact of void areas (i.e. holes) on medical application routing efficiency, we propose a new oriented void avoidance mechanism for wireless sensor networks embedded in medical environment. To choose the forwarding region (clockwise or anticlockwise) around the void, proposed mechanism is guided by the destination location with respect to the void. Our mechanism uses the right-hand rule to discover boundary nodes of the void and geometric formulas to obtain the forwarding region of a source node near the void. This node reduces its forwarding candidate set according to its already obtained forwarding region. Proposed approach is simple to implement, economic and could incorporate various other optimizations studies. Simulation results showed the effectiveness of the proposed mechanism which gives better performance compared to traditional schemes.
