Lifetime Modeling of a Sensor Network
ثبت نشده
چکیده
Lifetime of a sensor network is defined as the time after which certain fraction of sensor nodes run out of their batteries, resulting in a routing hole within the network. We develop a mathematical model for the lifetime of a sensor network when the data generation events within the network are spatially and temporally independent. Using this lifetime model, we introduce an efficient routing strategy such that an optimal lifetime can be achieved. Through simulations, we validate the analytical model with respect to lifetime of linear and planar sensor networks.

متن کاملEnergy-Saving in Wireless Sensor Networks Based on Optimization Sink Movement Control
A sensor network is made up of a large number of sensors with limited energy. Sensors collect environmental data then send them to the sink. Energy efficiency and thereby increasing the lifetime of sensor networks is important. Direct transfer of the data from each node to the central station will increase energy consumption. Previous research has shown that the organization of nodes in cluster...
