Packet deliv ery typically requires more than one hop. In each hop, we assume that transmission occurs in a time-slotted manner as illustrated in Figure 11.

1. The source, the relays (intermediate nodes), and the destination constitute an active route. We assume an end-to-end mechanism that enables a source node to know whether the packet has been delivered successfully.

The source node can observe whether there is a packet drop in one particular active path. However, the source node might not know where the packet is dropped. Finally, we assume that the routing decision has already been made before optimizing the packet-forwarding probabilities.

1 Let s denote the set of sources and destinations as {Si , Di }, for i = 1, 2, . . .

, M, where M represents the number of source destination pairs active in the network. Suppose that the shortest path for each source destination pair has been discovered. Let s n 1 2 denote the route/path as Ri = Si , f Ri , f Ri , .

. . , f Ri , Di , where Si denotes the source n 1 2 node, Di denotes the destination node, and f Ri , f Ri , .

. . , f Ri is the set of intermediate/relay nodes, thus, there are n + 1 hops from the source node to the destination node.

Let V = {Ri : i = 1, . . .

, M} be the set of routes corresponding to all source destination pairs. Let s denote further the set of routes where node j is the source as V js = {Ri : S(Ri ) = j, i = 1, . .

. , M}, where S(Ri ) represents the source of route Ri . The power expended in node i for transmitting its own packet is Ps(i) =.

r Vis S(r ) K d(S(r ), n(S(r ), r )) ,. (11.1). where S(r ) is the tr ansmission rate of source node S(r ), K is the transmission constant, d(i, j) is the distance between node i and node j, n(i, r ) denotes the neighbor of node i on route r , and is the transmission path-loss coef cient. For the link from node i to its next hop n(i, r ) on route r , K d(i, n(i, r )) describes the reliable successful transmission power per bit transmission. We note that (11.

1) can also be interpreted as the average signal power required for successful transmission of a certain rate S(r ) . This implies that transmission failure due to the channel fading has been taken into account by the transmission constant K . Let i for i = 1, .

. . , N be the packet-forwarding probability for node i.

Here, we use the same packet-forwarding probability for every source destination pair for following reasons. First, given the assumption of greediness of the nodes, there is no reason for one particular node to forward some packets on some routes and reject forwarding other packets on other routes. Second, the use of different packet-forwarding probabilities on.

1 We note that it is al swing qr bidimensional barcode ways possible for nodes to carry out manipulation in the routing layer. However, that is. beyond the scope of thi s chapter. For more information, please refer to [408]..

11.2 The system model and design challenge different routes will o nly complicate the deviation detection of a node and will not change the optimization framework discussed in this chapter. So, in our rst step to analyze the problem, we assume the same forwarding probability on every route. In future work, we will also be exploring the case in which the nodes use different packetforwarding probabilities for different routes.

Clearly, the probability of successful transmission from node i to its destination depends on the forwarding probabilities employed in the intermediate nodes and it can be represented as. i PTx,r = j (r \{S(r )= QR Code 2d barcode for Java i,D(r )}). (11.2). where D(r ) is the dest spring framework Denso QR Bar Code ination of route i and (r \ {S(r ) = i, D(r )}) is the set of nodes on route r excluding the source and destination. Let us de ne the good power con(i) sumed in transmission node i, Ps,good as the product of the power used for transmitting node i s own packet and the probability of successful transmission from node i to its destination, Ps,good =.
