Geographical and Topology Control-Based Opportunistic Routing for Ad Hoc Networks

Abstract

The opportunistic routing has great advantages on improving packet delivery probability (𝑷 𝒔𝒄 ) between the source node and candidate forwarding set. For improving 𝑷 𝒔𝒄 and reducing energy consumption and network interference, in this paper, we propose an efficient and reliable transmission power control based opportunistic routing (ERTO) for wireless ad hoc networks. In ERTO, the network interference and fading, which are critical to routing performances but not taken into account in previous works, are considered during the prediction of 𝑷 𝒔𝒄 . The 𝑷 𝒔𝒄 , the expected energy consumption, and the relationship between transmission power and node degree are considered to optimize the optimal transmission power and forwarding node degree jointly. For improving routing effectiveness and reducing computational complexity, we introduce the multi-objective optimization and Pareto optimal into ERTO. During the routing process, nodes calculate the optimal transmission power and forwarding node degree according to the properties of the Pareto optimal solution set. Based on these innovations, the energy consumption, the transmission delay, and the throughout have been improved greatly.

Energy-Efficient Opportunistic Routing Algorithm for Post-Disaster Mine Internet of Things Networks

“…Zhao et al [ 24 ] proposed an opportunistic routing algorithm based on trust relationships for wireless mesh networks (WMNs) to solve the problem of low message delivery rate and high network resource consumption when forwarding messages in opportunistic networks. Li et al [ 25 ] proposed an efficient and reliable transmission power control-based opportunistic routing (ERTO) for wireless ad hoc networks to improve packet delivery probability and reduce energy consumption and network interference. In ERTO, the packet delivery probability, the expected energy consumption, and the relationship between transmission power and node degree are applied to optimize the transmission power and forwarding node degree jointly.…”

“…Li et al [21] have introduced an efficient and reliable transmission power control-based OR (ERTO) to enhance packet delivery probability (Psc), while simultaneously reducing energy consumption and network interference. They considered Psc, expected energy consumption, and the relationship between transmission power and node degree to optimize both the transmission power and forwarding node degree, which are conflicting objectives.…”

“…( 22) will be terminated if the update error Er(k) < 10 −7 , or any element p j (k + 1) ≤ 0 of p(k + 1), or any element T I,J (k + 1) < 0 of T(k + 1), where p j (k + 1) ≤ 0 or T I,J (k + 1) < 0 indicates the update process of Eq. (22) will move in the wrong direction.…”

“…Moreover, an OR considering both global and localized optimizations is proposed for the dependent dutycycled wireless sensor networks in order to minimize the endto-end latency [21]. For realizing the tradeoff between routing effectiveness and computational complexity, multi-objective optimization and Pareto Optimality is introduced into the power control-based OR for wireless ad hoc networks [22]. Similarly, in order to reduce the transmission delay and avoid duplicate transmission in wireless multi-hop networks, an OR utilized the network-based candidate forwarding set optimization scheme is introduced in [23].…”
