Network Lifetime Maximization in Wireless Mesh Networks for Machine-to-Machine Communication
In this paper we present new optimization formulations for maximizing the
network lifetime in wireless mesh networks performing data aggregation and
dissemination for machine-to-machine communication in the Internet of Things.
We focus on heterogeneous networks in which multiple applications co-exist and
nodes may take on different roles for different applications. Moreover, we
address network reconfiguration as a means to increase the network lifetime, in
keeping with the current trend towards software defined networks and network
function virtualization. To test our optimization formulations, we conducted a
numerical study using randomly-generated mesh networks from 10 to 30 nodes, and
showed that the network lifetime can be increased using network reconfiguration
by up to 75% over a single, minimal-energy configuration. Further, our
solutions are feasible to implement in practical scenarios: only few
configurations are needed, thus requiring little storage for a standalone
network, and the synchronization and signalling needed to switch configurations
is low relative to each configuration's operating time.Comment: Ad Hoc Networks, in pres
