Resource allocation algorithm for WMSN Algorithm 3. 3 Multi-constrained QoS Routing The objective of QoS routing is to find a path from a source s to a destination d using the minimum amount of network resources such as energy consumption per route, residual battery power per node, available time slots, while satisfying various QoS constraints, such as delay, reliability, etc. When multiple routing metrics are considered, the problem becomes a multi-constrained path problem, which has been mathematically proven in [7] to be NP-complete.

However, in MobileCOP nodes are moved only after the first path is computed then-after, nodes memorize the path which will be used in future transmissions. Therefore, energy added at subsequent route computation results only from sending cost. Results show that Routing on the move and M ove(r) converge quickly since they use the same path after computing the first 3 consecutive routes from S to D. Since MobileCOP does not take into account the moving energy consumption in its routing decision, the distance moved by each node is the same for each model, but has different costs.

As Sleep/Wake scheduling problem, the resource allocation is also in joint correlation with routing process and application requirements.
