Geocasting in wireless sensor and ad hoc networks means delivering a message from a source node to all the nodes in a given geographical region. The objectives of a geocasting protocol are two-fold: guaranteed message delivery and low transmission cost. Most of the existing protocols do not guarantee message delivery, and those that do, incur high transmission costs. In this study, we propose the...
Geocasting in wireless sensor networks and ad hoc networks is the delivery of a message from a source to all the nodes in a given geographical region. The objectives of a geocasting protocol are two-folds: guaranteed message delivery and low transmission cost.

In wireless mobile ad hoc networks (MANETs), energy is a crucial resource. Topology control technology allows network nodes to reduce their transmission power while preserving the network connectivity. A MANET is a non-cooperative system so that only when a node earns its payment, which can cover its cost, the cooperation can be stimulated. We design a truthful topology control mechanism (TRUECON)...
