An Energy-Saving Routing Algorithm for Opportunistic Networks Based on Asynchronous Sleep Approach

Abstract

The sparse and mobility of nodes in opportunistic networks will cause network topology often fracturing, resulting that a large number of isolated nodes appear in opportunistic networks. These isolated nodes will waste much energy at idle listening stage, so this paper proposes an Efficient Routing algorithm for opportunistic networks based on Asynchronous Sleep Approach-ERASA. ERASA achieves the goal of saving energy by making the isolated nodes enter the low power consumption dormancy state. Then they will be timely awaken when there are other nodes entering into their communication range. Compared with the classical Epidemic routing algorithm, the several aspects performance of ERASA algorithm are improved such as network lifetime.

A history-based energy-efficient routing protocol for opportunistic networks

“…To the best of our knowledge, only few energy-aware routing schemes for OppNets have been investigated in the literature [50], [51], [52], [53], [54], [55], [56], [1].…”

“…In [55], Yao et al investigated the energy consumption wastage caused by the presence of a large number of isolated nodes in a sparse OppNet topology at the idle listening stage.…”

Energy aware routing for efficient green communication in opportunistic networks

“…Similar to the power-aware PRoPHET, energy-efficient PRoWait, and power-aware EDR routing algorithms, the proposed E-ATDTN protocol has been introduced by accepting the aforementioned attributes. Representative recent work on power-efficient routing mechanism in these networks [9][10][11][12][13][14][15][16][17] are discussed as follows.…”

“…In [14], the author propounded the wastage of power consumption that usually occurs in sparse OppNets at the inactive listening phase and presented a power‐efficient routing mechanism for OppNets. This mechanism worked on an asynchronous sleep method.…”
