where [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII] is the time for WCV to travel from node i to node i + 1, [P.
2] WCV needs to wait for some time WT(i) after arriving at node i at [t.
3]), WCV charges the node as soon as it arrives at the rate of [U.
Full], to achieve equation (22), WCV must charge sensor node within a distance and we could get this distance by solving D(i) in equation (3).
The arrival position of WCV at node i is updated by letting position(i).
Again, to accord with the energy dynamics in renewable cycles, we need to adjust the speed of WCV from node i to its next destination, e.
The base station in our simulation environment is located at (570,590)(in m) and the service station for WCV is at (50,50)(in m).
In our our simulation we let the WCV follow the counter clockwise direction and get total travel length [D.
Given a partition scheme and the initial position of WCV in each subarea (a WCV serves in only one subarea), we can work out the renewable cycles including T, [T.
Preventive care such as WCVs promotes children's health and well-being.
In fact, children who do not receive an adequate number of WCVs are at increased risk for not completing the vaccination schedule (Freed et al.
Like receipt of immunizations, receipt of WCVs appears to be associated with mothers' prenatal care initiation.
