MIP can provide better quality of service(QoS) in heterogeneous environment if it relies on layer 3 based movement detection techniques. Among the existing movement detection algorithms (MDAs), enhanced lazy cell switching (ELCS) provides better performance pared to eager cell switching(ErCS) and early cell switching (EyCS) by reducing movement detection delay when the mobile node (MN) crosses the overlapping cells. On the other hand, movement detection delay incurred by ErCS is always low pared to ELCS while the MN crosses adjacent cells. Thus, in this paper we propose a new MDA by retaining the positive features of ErCS and ELCS to provide better QoS in a work that prises overlapping cells and adjacent cells. Our proposed MDA reduces the usage of radio resources of the MN and foreign agent (FA) in overlapping zone pared to simulation results on NS2 demonstrates that our proposed MDA improves the performance of MIP as pared to other MDAs in terms of number of TCP data packets received by the MN, TCP throughput and amount of data transferred during simulation while MN crosses the overlapping area of two cells as well as when it roams in a work consisting of both types of cells overlapping and adjacent. ⑨ 【作 者】 Isvand, D.。 Chegini, .。 Salaripanah, A. 7 【機(jī) 構(gòu)】 Department of Mathematical Sciences, Isfahan University of Technology, Isfahan, 8415683111, Iran 【篇 名】 Numerical solution of the Schr246。dinger equations by using Deltashaped basis functions 【來(lái) 源】 Nonlinear Dynamics, p 117, 20xx 【類(lèi) 型】 Compendex 【摘 要】 Numerical simulations of the nonlinear Schroamp。die。dinger equ ations are studied using Deltashaped basis functions, which recently proposed by Reutskiy. Propagation of a soliton, inter action of two solitons, birth of standing and mobile solitons and bound state solutions are simulated. Some conserved quantities are puted numerically for all cases. Then we extend application of the method to solve some co pled nonlinear Schroamp。die。dinger equations. Obtained systems of ordinary differential equations are solved via the fourthorder RungeKutta method. Numerical solutions coincide with the exact solutions in desired machine precision and invariant quantities are conserved sensibly. Some parisons with the methods applied in the literature are carried out. ⑩ 【作 者】 Aghvami, Hamid。 Amani, Mojdeh 【機(jī) 構(gòu)】 National University of Sciences and Technology, Pakistan 【篇 名】 A survey on mobile data offloading: Technical and business perspectives 【來(lái) 源】 IEEE Wireless Communications, v 20, n 2, p 104112, 20xx 【類(lèi) 型】 Compendex 【摘 要】 Over the last few year
