A mobile ad hoc network (MANET) is a collection of mobile nodes where each node is free to move about arbitrarily. The Ad Hoc On-Demand Distance Vector AODV) routing protocol is one of the well-known and efficient on-demand MANET protocols. AODV currently does not support Quality of Service (QoS) and also has no load balancing mechanism. We propose some enhancements to the AODV protocol to prov...

We have designed a scalable and expressive naming system called SENS, capable of retrieving information of computing and content resources distributed widely across the Internet through exact queries and multi-attribute range queries over resource names. Our system utilizes a descriptive naming scheme to name resources and a multi-dimensional resource ID space for message routing through an ove...

Location-based services for mobile devices, such as route-planners, access data with spatial and temporal characteristics. How to balance the workloads for location-based services is an open problem. To investigate viable load-balancing mechanisms, we designed, implemented and measured a distributed, spatial cache overlay for two-dimensional, geographic data. In this paper, we describe an exper...

Mobile ad hoc network is a collection of wireless mobile nodes, such devices as PDAs, mobile phones, laptops etc. that are connected over a wireless medium. There is no pre-existing communication infrastructure (no access points, no base stations) and the nodes can freely move and self-organize into a network topology. Hence, balancing the load in a MANET is important because the nodes in MANET...

Pull systems focusing on throughput time control and applicable in situations with high variety and customization are scarce. This paper compares pull systems that can cope with such situations: POLCA and CONWIP. Both systems constrain the maximum amount of work in progress (WIP) within a loop, but their effectiveness in terms of reducing total throughput time is questioned. They mainly differ ...

Wireless networks such as Mobile AdHoc Networks (MANETs) have many advantages compared to wired networks. In MANETs the communication is not limited to a certain geometrical region. Swarm Intelligence based ACO algorithms provide interesting solutions to network routing problems. ACO based routing in MANETs will enhance the reliability and efficient packet delivery. They help in reducing contro...

The sizes of the BGP routing tables have increased by an order of magnitude over the last six years. This dramatic growth of the routing table can decrease the packet forwarding speed and demand more router memory space. In this paper, we explore the extent that various factors contribute to the routing table size and characterize the growth of each contribution. We begin with measurement study...

The lifetime of a network is the key design factor of mobile ad hoc networks (MANETs). To prolong the lifetime of MANETs, one is forced to attain a tradeoff of minimizing the energy consumption and load balancing. In MANETs, energy waste resulting from retransmission due to high bit error rate (BER) and high frame error rate (FER) of wireless channel is significant. In this paper, we propose tw...
