Multi-Constrained QoS Opportunistic Routing by Optimal Power Tuning in Low Duty-Cycle WSNs
Designing a multi-constrained QoS (Quality of service) communication protocol for mission-critical applications that seeks a path connecting source node and destination node that satisfies multiple QoS constrains such as energy cost, delay, and reliability imposes a great challenge in Wireless Sensor Networks (WSNs). In such challenging dynamic environment, traditional routing and layered infra...
متن کاملJoint Duty Cycle Scheduling, Resource Allocation and Multi-constrained QoS Routing Algorithm
Wireless mesh sensor networks (WMSNs) have recently gained a lot of interest due to their communication capability to support various applications with different Quality of Service (QoS) requirements. The most challenging issue is providing a tradeoff between the resource efficiency and the multiconstrained QoS support. For this purpose, we propose a cross-layer algorithm JSAR (Joint duty cycle...
متن کاملEfficient Flooding-Based Routing Protocol with Random Wake-Up for Very Low Duty-Cycle WSNs
Wireless sensor networks are used in many environmental monitoring applications (e.g., to monitor forest fires or volcanoes). In such applications, sensor nodes have a limited quantity of energy, but must operate for years without having their batteries changed. The main mechanism used to allow nodes to save energy is to sequence periods of activity and inactivity. However, the design of MAC an...
متن کاملOpportunistic Routing in Low Duty-Cycled Wireless Sensor Networks
Opportunistic routing is widely known to have substantially better performance than unicast routing in wireless networks with lossy links. However, wireless sensor networks are heavily duty-cycled, i.e. they frequently enter sleep states to ensure long network life-time. This renders existing opportunistic routing schemes impractical, as they assume that nodes are always awake and can overhear ...
متن کاملExact Algorithms for Multi-Constrained QoS Routing
The modern network service of finding a feasible or an optimal path subject to multiple constraints on performance metrics such as delay, jitter, loss probability, etc. gives rise to the multi-path constrained (MCP) or multi-constrained optimal-path (MCOP) QoS routing problems, which are NP-complete. In this paper, these problems are solved through exact algorithms. Even though exact algorithms...
