DTN mobile nodes depend on their mobility to carry the message to destination. Therefore it is important to understand the effect of buffer management policies on the performance of DTN routing protocols under different mobility models. In our previous work of DLA we examine that epidemic router was not showing good delivery probability in case of SPMBM. This paper is the performance of DLA (dr...

This paper presents an overview of IPv6-based mobility management protocols: mobile IPv6 (MIPv6), fast handovers for mobile IPv6 (FMIPv6), hierarchical mobile IPv6 (HMIPv6), and fast handover for hierarchical mobile IPv6 (F-HMIPv6). All these protocols play an important role in the next generation wireless networks, because in such networks, mobile users need to be freely change their access ne...

This paper presents a mobility tracking mechanism for IP-based networks. The Motivation behind proposed mechanism is that most of the mobile hosts tend to move locally within a limited geographical area. We have observed that a recently proposed mobility management scheme, called Dynamic hierarchical Mobile IP (DHMIP) performs better than MIP in terms of saving in signaling cost. But, it is not...

Electroacoustics and laser Doppler electrophoresis were employed to measure the mobility of surface-modified silica colloids in ethanol as a function of the ionic strength. Sufficiently low volume fractions were chosen to exclude effects of interparticle interactions. At high ionic strength, the electrophoretic mobility μ(e) is equal to the (electroacoustic) dynamic mobility μ(d) at 3.3 MHz. Ho...

In this paper, we propose an efficient mobility control algorithm for the downlink multi-cell orthogonal frequency division multiplexing access (OFDMA) system for co-channel interference reduction. It divides each cell into several areas. The mobile nodes in each area find their own optimal position according to their present location. Both the signal to interference plus noise ratio (SINR) and...

In multi-hop wireless network simulation, mobility model is one of the crucial factors affecting the performance of networks. This paper aims to analyze the spatial distribution of Random Waypoint mobility models with the progress of time. Additionally, we study the network performance of a random-based mobility model. The results from the evaluation show the uniform node distribution of Random...

Routing data from source to destination is hard in Mobile Ad-Hoc Networks (MANET) due to the mobility of the network elements and lack of central administration. The main method for evaluating the performance of MANETs is simulation. In this paper performance of Ad-hoc On-demand Distance Vector (AODV) reactive routing protocol is studied by considering IEEE 802.11 and IEEE 802.15.4 standards. M...

In Pocket Switched Networks (PSN), the similarity of mobility patterns of different human beings can be exploited to design routing protocols that have better packet delivery ratio and shorter end-to-end delay. However, current research lacks techniques to effectively quantify the similarity of human beings’ mobility behaviors as they exhibit diversities in both the time and spatial domains. In...

The present paper joins within the framework of research to optimize the Quality of Service (QoS) in the Mobile Ad Hoc Networks (MANET). In this paper, we have studied the impact of real-time VBR (H.263) traffic on the performances (End-toEnd Delay, Throughput and Packet Delivery ratio) of routing protocols DSDV (Dynamic DestinationSequenced Distance-Vector) and AODV (Ad Hoc On-Demand Distance-...

In this paper we have evaluated the performance of VDGEDIR, CH-MFR, R-DIR, DREAM and LAR geocasting protocol proposed for mobile ad hoc networks. The performance has been compared in both static and mobile environment. In the static environment we have also considered SP algorithm to compare performance of geocasting algorithms with SP. Mobility is introduced using random walk mobility model. I...
