1. A method for maximizing residual power along routes in a wireless network including a plurality of battery operated nodes, comprising:

  • discovering a plurality of routes from a destination node to a source node via intermediate nodes of the network using dynamic source routing (DSR);

    measuring a residual power in the battery of each intermediate node;

    determining a power cost associated with each route according to the residual power of the intermediate nodes;

    selecting a particular route for transferring data from the source node to the destination node, the particular route having a least power cost;

    including the particular route in a routing table in a packet, in which the routing table is an ordered list of intermediate node addresses;

    determining a delay cost associated with each route;

    selecting a particular route having a least delay cost; and

    including the least delay cost in each transmitted packet; and

    transmitting each packet in the network using the DSR, and in which each packet includes the routing table.
