A Dynamic Clustering and Energy Efficient Routing Technique for Sensor Networks- IEE TRANSACTIONS ON WIRELESS COMMUNICATIONS, VOL. 6, NO. 8,
Glomosim

Abstract
In the development of various large-scale sensor systems, a particularly challenging problem is how to dynamically organize the sensors into a wireless communication network and route sensed information from the field sensors to a remote base station. This paper presents a new energy-efficient dynamic clustering technique for large-scale sensor networks.

Energy efficiency is one of the major concerns in wireless sensor networks as the network lifetime depends on it. This article investigates the relationship between the sensor network performance, particularly its lifetime, and the number of active reporting nodes N. The analytical and simulation approaches are both used in this process. decreasing the number of reporting nodes
increases the number of reports which are to be sent to the sink if a desired information reliability about a detected event is to be achieved. If the the number of re ....etc

Performance Evaluation of Efficient and Reliable Routing Protocols for Fixed-Power Sensor Networks

ABSTRACT
A Fixed power wireless sensor networks are cost effective and prevalent, and they are facing lots of problems like RF interference, node failure from environmental noise and energy constraints. A routing protocol for Fixed power wireless sensor networks must overcome these problems. Because it have to achieve reliability, energy efficiency and scalability in message delivery. In this paper, we propose an efficient and ....etc
