A Cross-Layer Wireless Sensor Network Energy-Efficient Communication Protocol for Real-Time Monitoring of the Long-Distance Electric Transmission Lines

Algorithm 1

Break-routing establishment.

Input:

  PanNode, RoutingNode, RREQ, Node;

Initialize:

  RREQ = request_packet(PanNode);

  RREQ = receive_packet(RoutingNode);

  RoutingNode.previous = PanNode.address;

  RoutingNode.Transpond(RREQ);
