Abstract

Currently, IEEE 802.11 standard for ad-hoc wireless mode is inadequate for multi-hop network. Recent efforts for the advancement of 802.11 standards, such as 11e for QoS support and 11n for high data rates (> 100 Mbps), are still limited as they are dependent on the wired infrastructure backbone and single-hop wireless communication. One major challenge in quality-of-service (QoS) oriented routing in wireless ad-hoc networks is to find a route that satisfies multiple constraints including energy consumption minimization, delay, node failure and throughput maximization. In this paper, we propose a novel Dynamic Energy Efficient Routing (DEER) protocol that guarantees message delivery, maximum network lifetime and message flow. DEER uses those specific nodes on the fly which has maximum residual energy above a defined energy level for relaying message from a source to a destination. Our proposed approach has been evaluated using realistic channel model and it demonstrates improved session lifetime and efficient data flow compared to Probabilistic Energy Profile, Efficient Hop Count Routing, Dijkstra and Random/opportunistic algorithms. In addition, DEER can lend itself easily to battery-based sensor networks or energy-harvested based sensor networks.

无线传感器网络中的动态节能路由协议

摘要

当前，用于ad-hoc无线模式的IEEE 802.11标准不足以用于多跳网络。由于802.11标准依赖于有线基础架构骨干网和单跳无线通信，因此近期为提高802.11标准而进行的努力仍然受到限制，例如11e用于QoS支持和11n用于高数据速率（> 100 Mbps）。无线自组织网络中面向服务质量（QoS）的路由的一个主要挑战是找到一种满足多种约束条件的路由，包括最小化能耗，延迟，节点故障和吞吐量最大化。在本文中，我们提出了一种新颖的d ynamic Ë NERGY Ë fficient ř郊游（鹿）协议，以确保消息传递，最大的网络生存期和消息流。DEER会动态使用那些具有最大剩余能量（高于定义的能量水平）的特定节点，以将消息从源中继到目的地。我们提出的方法已经使用现实的信道模型进行了评估，并且与概率能量曲线，有效跳数路由，Dijkstra和随机/机会算法相比，具有更长的会话寿命和有效的数据流。此外，DEER可以轻松地应用于基于电池的传感器网络或基于能量收集的传感器网络。
