Sustaining the emergency wireless multihop infrastructure by distributed sharing of energy consumption

Wireless multihop infrastructures WMIs facilitate low-cost and quick deployable network infrastructures for emerging applications in emergency responses and smart cities. Cooperative sharing of energy consumption is essential for network sustainability. This paper studies the problem of cooperative sharing of routing services in an emergency WMI E-WMI by examining the regulation of route switching from perspectives of network-wide and long-time energy efficiency. A key idea in the regulation of route switching is employing explicit routing terms among base stations in an E-WMI, allowing tolerance of temporary imbalance of energy consumption in the network. A routing term refers to a period for a base station to continuously serve routing in an E-WMI. By taking into account the specific features of E-WMIs, this paper overcomes the challenging problems of complexity and difficulty in examining the explicit route switching and energy distribution in multihop networks. We find that there exists the optimal routing term and number of route switching for the long-time energy efficiency. With the optimal routing terms, a network can take a principle of distributed energy sharing by route switching management rather than only applying end-to-end energy-efficient routing that does not have a long-time management of network energy consumption.
