A. Assumptions of MEL-AODV protocol
1. The node has randomly distributed initial energy
level, movement and position.
2. The node’s link layer read the power information from
the physical interface and could reply to the network
layer.
3. Wireless channel is bidirectional and symmetrical, in
other words, while the two nodes are communicating,
the signal attenuation is the same.
Based on the assumptions above the remaining energy
level of the network nodes can be extracted when
network nodes send and transmit packets among each
other. Most of the routing protocols only consider delay,
data delivery, loss ratio, but neglect the energy remain in
the nodes along the link, causing the partial nodes
repeatedly to appear in many routes and prematurely
“death”. The proposed routing protocol always chooses
the highest energy route in route table for data
transmission, thus energy consumption of nodes in the
network could be effectively balanced and the average
survival time of nodes in the network could be improved.
