Wireless Signal Strength Topology Maps in Mobile Adhoc Networks

The ability to predict the future communication capability between two or more autonomous wireless nodes is an important issue to any wireless adhoc routing protocol that predicts changes to network topology before they happen. While many wireless adhoc routing protocols focus only on known information, emerging protocols are utilizing predicted information of the future topology as a means of improving their efficiency. This paper proposes a new concept for signal mapping which is able to predict the expected signal loss between any two locations in a local area, improving on previous signal mapping algorithms by taking into consideration boundaries between areas. Simulations of the model are presented to verify the concept and algorithm presented.
