For these stencil computations involving shifts, individual calls to send and recv primitives are very efficient.

Here, we concentrate on the computation of a communication set called RECV. The actual send and recv sets used by the code generator are produced in a later pass of the compiler from the RECV sets discussed here using two projection functions as explained in Section 5.

[N.sub.n] be the number of source nodes Let [N.sub.ie] be the residual energy of source nodes Let CH be the cluster head CH() { If([N.sub.ie] is the highest among all other [N.sub.i-1]) Elect [N.sub.i] as CH(); Else [N.sub.i] is simpleSensorNode(); } [N.sub.i]() { sendRouteRequest(); recv RouteReply(); forwardPacketToNeighbor(); } GN() { switch(Case) Case 1: Flooding { sendLargeNumberOfFakeRouteRequest();} Case 2: Blackhole { sendfakeRouteReply(); disableRouteError(); recvPackets(); dropPackets(); } Case 3: Grayhole { sendfakeRouteReply(); disableRouteError(); recvPackets(); dropPackets for an interval [T.sub.b] (); } } Flooding attacker node exhausts the network resources in terms of bandwidth and energy.
