1. BSNL- Road Ahead

Authors -  T. Lavanya Kumari

Abstract : Liberalization has brought many challenges for the Government of India enterprise in Telecom Sector i.e. Bharat Sanchar Nigam Limited (BSNL). BSNL known as Department of Telecommunications had been a near-monopoly during the socialist period of the Indian economy. During this period, BSNL was the only telecom service provider in the country. In spite of owning extensive and robust network across India and having leadership position in the telecom space till 2008, the present situation has become tough for state owned operator BSNL. Now BSNL is struggling to maintain the tempo and its foothold in the industry. Over a few past years the company’s position is being deteriorated. BSNL‟s market share in 16 out of 22 circles not by a significant margin due to poor performances over past two to three years. In August 2010, more than 2 lakh BSNL land line subscribers got their lines disconnected. While a good many mobile subscribers are also shifting to other service providers because of many reasons. The market has opened up for telecom services and every company is struggling to capture maximum share of the growing market. Different strategies are being formulated to ensure the growth in customer base. In this paper, we have carved out a comprehensive study pertaining Indian Telecom market and position of BSNL in the Indian Telecom sector.

2. AN ADAPTIVE WSN CLUSTERING SCHEME USING LION OPTIMIZATION ALGORITHM TO MAINTAIN COVERAGE AREA IN WIRELESS SENSOR NETWORK

Authors -  K. Thenmozhi, S. Udhaya,N. Vinothini, V. Nagaraju

Abstract : Wireless sensor networks (WSNs) are composed of hundreds or thousands of sensor nodes in order to detect and transmit information from its surrounding environment. The sensor nodes have limited computation capability, limited power and small memory size. In these networks, sensor nodes are dependent on low power batteries to provide their energy. As energy is a challenging issue in these networks, clustering models are used to overcome this problem. Hence, many metaheuristic algorithms have been developed over the last years. Many of these algorithms are inspired by various phenomena of nature. In this paper, a new population based algorithm, the Lion Optimization Algorithm (LOA), is introduced. Special lifestyle of lions and their cooperation characteristics has been the basic motivation for development of this optimization algorithm. Some benchmark problems are selected from the literature, and the solution of the proposed algorithm has been compared with those of some well-known and newest meta-heuristics for these problems. The obtained results confirm the high performance of the proposed algorithm in comparison to the other algorithms used in this paper.

Keywords : Wireless Sensor Network, Lion Optimization Algorithm (LOA), Metaheuristic.
