  2. propose • Prolong Sensor Network Lifetime • Find max network lifetime • Consider two part: Data routing, charging path

  3. Routing Cost • Nodes periodically broadcast beacons The beacons are broadcasted periodically, nodes can dynamically change their parents. • Receiving the costs from neighbor nodes, sensor nodeicalculates it‘senergy-minimum routing cost c’i node i routing cost ETXi,j ,t number of transmissions needed to send a packet successfully over link (i, j).

  4. Charge aware routing cost • Esis the battery capacity • ei,j,t = Charge energy estimates the nodal energy consumption rate

  5. Charging Scheduling • First, selects a set of sensor nodes that should be charged in the next Tc interval. Secondly, it determines a sequence in which the sensor nodes are charged so that the movement time is minimized. • Maximize • ρi be the percentage of charging energy that should be allocated to sensor node i in one Tc interval.

  6. Future nodal energy consumption rate C i,t= erx andetxexpected energy consumed to transmit and receive a packet Si,tthe set of energy-minimum paths from sensor node i to the sinkrj,t future sensory data packet generation rate of node i estimated at time t

  7. Charging sequence • Merge • VRPTN

  8. prototype system

  9. Optimal solution • 0 • the MC’s movement delay is ignored and the link qualities are perfect Life time Flow constraint Total charge time

  10. Conclution
