Apparatus, method, and system for a destination cached routing protocol for mobile ad hoc networks

摘要

An apparatus, system and method are disclosed for a destination cached routing protocol for data transmission among a plurality of nodes in a mobile ad hoc network. When a routing request is received, an intermediate node transmits a received routing request message to neighboring nodes, and appends its address to and forwards the routing request packet only to other nodes from which a received routing request message was not received during a first predetermined period of time. When a route reply packet is received, the designated data transmission route is stored in memory as a cached data transmission route to the destination node, and a cached route message is transmitted to neighboring nodes, which also store the data transmission route. Upon a link failure, alternative data transmission routes are stored in memory and may be utilized to continue data transmission without additional route discovery.

1. A method for a destination cached routing protocol for data transmission in a mobile ad hoc network, the method performed by a plurality of data processing apparatus as a plurality of nodes of the mobile ad hoc network, the method comprising:
using a source node, transmitting a routing request packet for a data transmission route from the source node to a destination node of the plurality of nodes; when a routing request is received, using an intermediate node of the plurality of nodes, transmitting a received routing request message to neighboring nodes of the plurality of nodes; using the intermediate node, appending the intermediate node address to the routing request packet and forwarding the routing request packet only to other nodes, of the plurality of nodes, from which a received routing request message was not received during a first predetermined period of time; using a destination node, for each route request packet received by the destination node, transmitting a route reply packet having a designated data transmission route between the source node and the destination node; and transmitting a data packet, the data packet having the designated data transmission route in a packet header.
