Abstract
An exemplary node of a network, such as a wireless sensor network, has a communication device and a stack. The communication device is configured to receive a multicast message from a channel of a wireless sensor network. The communication device is further configured to transmit an energy level signal indicative of an amount of energy detected for the channel while the multicast message is being received by the communication device. The stack is configured to determine whether to retransmit the multicast message through the wireless sensor network based on the energy level signal.
Claims12
A node for communicating multicast messages in wireless sensor networks, comprising:
- a communication device configured to receive a multicast message from a channel of a wireless sensor network, wherein the multicast message is to be communicated to a plurality of nodes of the wireless sensor network, the communication device further configured to transmit an energy level signal indicative of an amount of energy detected for the channel while the multicast message is being received by the communication device;
- and
- a stack configured to determine whether to retransmit the multicast message through the wireless sensor network based on the energy level signal.
A wireless sensor network, comprising:
- a first node configured to transmit a multicast message to be received by a plurality of nodes of a wireless sensor network;
- and
- a second node configured to receive the multicast message via a channel of the wireless sensor network and to determine a value indicative of an amount of energy detected for the channel while the multicast message is being received by the second node, wherein the second node is configured to determine whether to retransmit the multicast message through the wireless sensor network based on the value.
A wireless sensor network, comprising:
- a first node configured to transmit a multicast message to be received by a plurality of nodes of a wireless sensor network;
- and
- a second node configured to receive the multicast message and to determine a value indicative of a strength of the multicast message, wherein the second node is configured to determine whether to retransmit the multicast message through the wireless sensor network based on the value.
A method for communicating multicast messages in wireless sensor networks, comprising the steps of:
- receiving a multicast message at a node of a wireless sensor network;
- determining a value indicative of a strength of the received multicast message;
- determining whether to retransmit the multicast message via the node through the wireless sensor network based on the value;
- and
- retransmitting the multicast message from the node through the wireless sensor network based on the determining whether to retransmit step.
