In infrastructure-based mobile ad hoc networks, every mobile node has to send registration message periodically to register with an Internet Gateway (IG) or update its presence. Since registration messages are delivered to an IG, the mobile nodes near an IG can be congested, thus experiencing a lot of collisions in message transmission. This phenomenon is called “funneling effect.” In this paper, we employ message aggregation technique to resolve the funneling effect and use a skewed time synchronization to maximize the message aggregation. We show by resorting to simulation that the message aggregation technique can alleviate the funneling effect greatly.
