Geographic routing in sensor and actuator networks
type: Dataset
description: This thesis is about wireless multi-hop networks such as wireless sensors networks or hybrid sensor/actuator networks and actuator networks. Those kinds of networks are composed of independent entities (nodes, i.e. the robots) which have very limited computing and memory capabilities. Moreover, they are battery powered and have to work in an efficient way. They communicate through the radio medium and do not require any static infrastructure. In order to relay messages between actuators up to the base station, we use what is called "routing protocols". In order to be efficient, those protocols have to find a routing path, over multiple robots, in a local and distributed manner, without any global knowledge about the network. My works rely on CoMNet, the first geographic routing protocol which relies on the controlled mobility of the robots while guaranteeing network connectivity despite their movements. CoMNet relocates next hop node on each routing step, according to a predefined relocation pattern. Its aims to adapt the network topology to the routed traffic in order to save energy. Nevertheless, CoMNet does not consider the consequences of those relocations more than in a one-hop way. By making node N relocating node N +1 on the routing path, CoMNet adapts the topology locally. But CoMNet ignores the fact that making this N + 1 node move changes its routing possibilities too. We proposed MobileR (Mobile Recursivity), a new routing protocol which takes this phenomena into account. MobileR, at each routing step, anticipates the routing in a multi-hop manner through computations over its one-hop neighbors. It makes the current forwarding node compute all the possible routing paths toward the destination using relocation patterns recursively. The cost-over-progress of each path is computed and the next hop selected is the first hop on the best computed path. Still, the protocol is completely localized and no information, except the forwarding packet, is shared betwee…
