When the cells in a location area are sequentially paged based on specific information, such as the last registered area or
a mobile speed, the paging load may be non-uniformly distributed among the cells. This non-uniform paging traffic causes an
additional paging delay due to the increased waiting time in cells that have a high paging load. In this paper, we introduce
a new paging strategy in which the paging sequence in a location area is optimized according to both the location probability
of a mobile terminal and the paging load distribution among the cells. In addition, we propose a simple polynomial-time heuristic
algorithm to determine sub-optimal paging sequence. Numerical results show that our proposed strategy has almost an equivalent
optimal performance and outperforms the conventional paging scheme with respect to a paging delay.

    ABSTRACT: IP-based IMT Network Platform(IP2) is an ubiquitous platform supporting mobility using two step IP address mode converting – IP host address(IPha) and IP routing address(IPra) – in a backbone network. Mobile Node(MN) in IP2 maintains its state as either active or dormant state, which is transferred to active state through Paging process when communication is required. In this paper, we proposed a Paging method using agent to resolve the problem of the conventional Paging method which transmits the Paging messages to all cells in Location Area(LA) resulting in the excessive use of network resources. Performance evaluation of the proposed method using NS-2 showed that the usage of network resources becomes more efficient by reducing Paging loads, especially under the condition of increased nodes.

    ABSTRACT: Mobility management in wireless cellular networks is one of the main issues for resource optimization. It is aimed to keep track of Mobile Stations (MSs) in the different Location Areas (LAs) or Registration Areas (RAs) for an efficient call delivery. The optimization issues of these location strategies look for a minimization of the generated signaling traffic. We describe the three basic strategies for location management: distance-based, time-based and movement-based, and their corresponding optimization cost. We emphasize that counting the number of wireless cell crossings or handovers occurring in the call duration time or during inter-call times is a fundamental issue for mobility management analysis. We present the main approaches in the literature to deal with these problems with a special emphasis to renewal theory to model the probabilistic structure of these optimization problems.

    ABSTRACT: This paper reports an investigation on the Bunsen reaction. An experimental campaign was conducted by means of a stirred reactor. Runs were carried out at a constant temperature in the 30–120 °C range, following a semi-batch procedure by feeding gaseous sulfur dioxide in an iodine/hydriodic acid/water solution. A specific analytical procedure to measure the hydriodic phase composition was implemented. It was observed that both the amount of absorbed SO2 and its conversion lowered as the temperature increased. Secondary reactions were beyond the detection limit in the reactor, even at low temperature and low iodine content. The purification of the produced hydriodic phase was also investigated. It was possible to satisfactorily reduce the impurities content without the occurrence of secondary reactions only when high temperature and high iodine content were applied.
