This work presents two speed based mobility models for gossip algorithms in wireless sensor networks. The corresponding upper bounds on the convergence time are derived, which show the relationship between speed of agents and convergence rate of gossip algorithms. The influences of speed are examined under both mobility models. Simulation results indicate that the speed based mobility model can offer...
Spatial query processing is important to the emerging mobile network applications such as ad hoc networks and mobile sensor networks. The conventional caching techniques are ineffective in dealing with spatial queries in dynamic environments due to the following reasons: first, the cache contents are described based on queries instead of data locations, which lead to the inefficiency in describing...
