Abstract
Little literature concentrates on effective and self-organizing regional energy-saving schemes in cellular networks with dynamic traffic. In this paper, we propose a regional self-organizing energy-saving management mechanism through pilot power adjustment in cellular networks. The mechanism analyzes autonomic processes for saving energy firstly. Then, it proposes regional BS TP (Trigonal-Pair) compensation method to determine BS modes for saving energy. Next, it adopts intelligent coverage compensation algorithm to adjust pilot power of compensated BSs, so as to avoid coverage hole and ensure enough capacity. Integrated evaluation model is still proposed in the mechanism to validate efficiency of proposed algorithms. Simulations show that about 17% of regional energy consumption can be saved. In comparison to other ES methods, our ES mechanism can obtain better energy-saving outcomes and keep service quality and coverage above acceptable levels.

Summary
Saving energy for cellular networks (including GSM, 3G, and LTE) contributes to reduction of greenhouse effect and curtailment of operating expense, which make sense of strong practical significance [1]. Management centre switches off several BS under low traffic period, and adjusts wireless parameters (such as pilot power and down tilt) of active BSs, so as to avoid coverage hole and guarantee users’ QoS (Quality of Service) demand [5]. This paper proposes a self-organizing pilot-power adjusting mechanism (SPAM) to save energy for cellular networks. It can obtain a better ES effect comparing to other methods and guarantee regional coverage and service quality as International Journal of Distributed Sensor Networks well. It proposes processes of autonomic ES management and key algorithms for coverage compensation It still considers regional interference and introduces a more integrated energy model.
