Abstract: Determination of a transmission through a network having a plurality of nodes using carrier sense multiple access collision avoidance (CSMA/CA) may be performed by broadcasting a route request (RREQ) packet from a source node that is targeted towards a destination node within the network, such that the RREQ is received by a first set of nodes in proximity to the source node. After first receiving a RREQ, each of the plurality of nodes rebroadcasts the RREQ after waiting a randomized amount of wait time. During each randomized wait time, the node suppresses all but one RREQ received by the node during the wait time.

Abstract translation: 通过使用载波侦听多址冲突避免（CSMA / CA）的具有多个节点的网络的传输的确定可以通过从目标为网络内的目的地节点的源节点广播路由请求（RREQ）分组来执行 ，使得RREQ由靠近源节点的第一组节点接收。 在首次接收到RREQ之后，多个节点中的每一个在等待随机的等待时间量之后重播RREQ。 在每个随机等待时间期间，节点在等待时间期间抑制节点收到的除了一个RREQ之外的所有节点。
