Opportunistic networks (OppNets) are modern types of intermittently connected networks in which mobile users communicate with each other via their short-range devices to share data among interested observers. In this setting, humans are the main carriers of mobile devices. As such, this mobility can be exploited by retrieving inherent user habits, interests, and social features for the simulati...

Wireless networks allow a more flexible communication model than traditional networks since the user is not limited to a fixed physical location. Unlike cellular wireless networks, ad hoc wireless networks do not have any fixed communication infrastructure. In ad hoc networks, routes are mostly multihop and network hosts communicate via packet radios. Each host moves in an arbitrary manner and ...

WLANs are currently being considered for use in the context of a larger geographical area such as a city or a campus due to their convenience, cost efficiency, and ease of integration with other networks. Due to support large numbers of portable devices and their dynamic relocation, wide WLANs must face problems of location management and network resource allocation. In order to solve these cha...

Mobile grids are one of the emerging grid types. They help to pool the resources of several cooperative mobile devices to resolve a computationally intensive task. Mobility management is a key challenge in mobile grids which includes mechanisms to track and maintain the locations of mobile nodes. Mobility prediction is one of the most important components of mobility management, which defined a...

An ad hoc wireless network is an infrastructureless network composed of mobile hosts. The primary concerns in ad hoc networks are bandwidth limitations and unpredictable topology changes. Thus, eecient utilization of routing packets and immediate recovery of route breaks are critical in routing and multicasting protocols. A multicast scheme, On-Demand Multicast Routing Protocol (ODMRP), has bee...

Connection admission control (CAC) and mobility management in cellular networks are solved separately in previous work. This paper presents a framework to solve these two problems together to get more effective solutions to both. The key component of this framework is a common mobility prediction scheme, which can be used in both locating/paging mobiles and making admission decisions. A novel C...

Mobility-on-demand (MoD) systems have recently emerged as a promising paradigm of one-way vehicle sharing for sustainable personal urban mobility in densely populated cities. In this paper, we enhance the capability of a MoD system by deploying robotic shared vehicles that can autonomously cruise the streets to be hailed by users. A key challenge to managing the MoD system effectively is that o...
