How to provide low energy consumption and high packet delivery ratio are considered the
major issues in the protocol design for the Wireless Sensor Networks (WSNs). The main focus
of this paper is to reduce the number of data transmissions within the WSNs for decreasing
the energy consumption of the sensor nodes. In the wired networks, the Steiner-Tree is
regarded as the optimal approach for constructing the multicast structure for specific senders
and receiver. However, the results can not be directly applied to the wireless environment. In
this paper, an Energy Conserving Multicast Routing (ECMR) protocol is proposed to reduce
the total number of relaying nodes for the construction of a multicast tree. It is designed to be
a heuristic scheme since achieving a minimal cost multicast tree is considered an NP-Hard
problem in the wireless broadcast environment. Moreover, the proposed algorithm is implemented on practical embedded platforms for performance evaluation. Comparing with
the existing multicast routing protocol, the experimental results show that the proposed
ECMR scheme can provide better energy conservation while the packet delivery ratio is still
preserved.
