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: We searched for the optimal compromised operating conditions for the Bunsen reaction of IS thermochemical water splitting, considering the key concerns of the IS cycle: the liquid–liquid equilibrium (LLE) phase separation performance, the characteristics of water distribution between the sulfuric acid (SA) phase and the poly-hydroiodic acid (HIx) phase, side reaction occurrence, and the effect on operating costs. Experimental data available from a literature survey were combined, and common trends were examined through a series of parametric studies. Based on the results, the optimal operating point and allowable operating window for the Bunsen reaction have been proposed: the optimal point is represented by 4 mol of excess iodine and 11 mol of excess water in the stoichiometry at temperature of 330 K, while the allowable window ranges over for the excess iodine, for the excess water, and for the temperature. After the Bunsen reaction and LLE phase separation, 5 mol of the excess water is distributed to the SA phase and to the HIx phase. Operating within this window makes it possible to avoid the side reaction and iodine solidification, to increase the HI concentration well above the azeotropic point in the HIx section, and to minimize operating costs arising from excess iodine and water.

    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.
