The Wireless Sensor Networks (WSNs) usually consist of several wirelessly connected sensors, to accumulate the data from some geographically scattered field and communicate it to a central database. Thus WSNs become an expedient tool to monitor the widespread gas distribution network such as Sui Northern Gas Pipelines Ltd. Pakistan. In this paper, some routing protocols performance has been investigated for gas pipeline monitoring applications. Simulated comparison of various routing protocols for WSNs deployed over gas distribution pipeline networks can give a valuable insight into the workability of the system, its performance, and other critical design parameters. The estimated lifetime of the network, node deployment for encyclopedic operation, the impact of energy harvesting from the field, and placement of the sink node at an optimal location are the key issues in the design of the WSN for pipeline network monitoring. All these issues are studied through simulation of various protocols for WSNs based upon real geographic locations of the nodes, real-world power levels and power consumptions by various processes of the wireless sensor networks. The simulations results show that DDEEC based WSN, for monitoring an actual Gas Distribution Network with a substantial quantity of nodes, can run with about 99.9% alive nodes for a benchmark period of 10 years. It was also evident from the comparison of the simulation results that the routing protocol DDEEC based system performs 0.4 to 34% better than the system based on LEACH, SEP, DEEC, and its other variants.

无线传感器网络（WSN）通常由几个无线连接的传感器组成，以累积来自某个地理分散字段的数据并将其传送到中央数据库。因此，WSNs成为监视广泛的天然气分销网络（如巴基斯坦Sui Northern Gas Pipelines Ltd.）的便捷工具。在本文中，已经针对天然气管道监控应用研究了一些路由协议的性能。对通过气体分配管道网络部署的WSN的各种路由协议进行的仿真比较，可以深入了解系统的可操作性，其性能以及其他关键设计参数。网络的估计寿命，百科操作的节点部署，现场能量收集的影响，将汇点节点放置在最佳位置是管道网络监控WSN设计中的关键问题。通过基于节点的实际地理位置，实际功率水平以及无线传感器网络的各种过程的功耗，通过对WSN的各种协议进行仿真来研究所有这些问题。仿真结果表明，基于DDEEC的WSN（用于监视具有大量节点的实际气体分配网络）可以在约10年的基准周期内运行约99.9％的活动节点。从仿真结果的比较中还可以明显看出，基于路由协议DDEEC的系统比基于LEACH，SEP，DEEC及其其他变体的系统性能提高0.4％至34％。通过基于节点的实际地理位置，实际功率水平以及无线传感器网络的各种过程的功耗，通过对WSN的各种协议进行仿真来研究所有这些问题。仿真结果表明，基于DDEEC的WSN（用于监视具有大量节点的实际气体分配网络）可以在约10年的基准周期内运行约99.9％的活动节点。从仿真结果的比较中还可以明显看出，基于路由协议DDEEC的系统比基于LEACH，SEP，DEEC及其其他变体的系统性能提高0.4％至34％。通过基于节点的实际地理位置，实际功率水平以及无线传感器网络的各种过程的功耗，通过对WSN的各种协议进行仿真来研究所有这些问题。仿真结果表明，基于DDEEC的WSN（用于监视具有大量节点的实际气体分配网络）可以在约10年的基准周期内运行约99.9％的活动节点。从仿真结果的比较中还可以明显看出，基于路由协议DDEEC的系统比基于LEACH，SEP，DEEC及其其他变体的系统性能提高0.4％至34％。无线传感器网络的各个过程的实际功率水平和功耗。仿真结果表明，基于DDEEC的WSN（用于监视具有大量节点的实际气体分配网络）可以在约10年的基准周期内运行约99.9％的活动节点。从仿真结果的比较中还可以明显看出，基于路由协议DDEEC的系统比基于LEACH，SEP，DEEC及其其他变体的系统性能提高0.4％至34％。无线传感器网络的各个过程的实际功率水平和功耗。仿真结果表明，基于DDEEC的WSN（用于监视具有大量节点的实际气体分配网络）可以在约10年的基准周期内运行约99.9％的活动节点。从仿真结果的比较中还可以明显看出，基于路由协议DDEEC的系统比基于LEACH，SEP，DEEC及其其他变体的系统性能提高0.4％至34％。
