The research in the field of service discovery in mobile ad-hoc networks is characterised by a lack of quantitative research. Many ideas have been put forward but few have been tested, either in simulation or real life. This paper fills part of that void, by comparing through simulation a simple broadcast-flood protocol, an integrated routing and service-discovery approach, and a global-knowled...

One feature common to most existing routing protocols for wireless multi-hop ad hoc networks, or MANETs, is the need to flood control messages network-wide during the route acquisition and maintenance process. Flooding of control messages may result in redundant broadcasts and cause serious contention and collision problems in MANETs. In this paper, we develop an analytical model to study the p...

Middleware solutions for sensor networks have so far mainly focused on communication abstractions, ad-hoc message routing protocols, and power conservation techniques. We argue that customisation and dynamic reconfiguration of sensor network middleware are additional important dimensions to consider. This paper describes a sensor middleware that can be customised to suit different sensor applic...

Peer-to-Peer (P2P) networks without central entities, such as Gnutella or JXTA, generally suffer under a high signaling load resulting in poor efficiency. The main reason therefore is the necessity to flood requests in the overlay, since in most P2P protocols the nodes are not provided with any information about the P2P overlay network topology. This paper therefore addresses this application-l...

[1] The last deglaciation was interrupted by three major cooling events, the Younger Dryas, the Preboreal Oscillation and the 8.2-ka cold event. As the Laurentide Ice Sheet retreated, different outlets from Lake Agassiz became available causing the proglacial lake to drain to a new level in a rather short timescale (flood) and divert continental runoff over hundreds of years (routing). Here we ...

The purpose of this study was to analyze the effect spillway width on flow elevation at weir crest based flood discharge design for Probable Maximum Flood (PMF) return period using routing hydrologically Cacaban Dam (Indonesia). rainfall Precipitation (PMP) uses Hershfield Equation. analysis QPMF used Nakayasu Synthetic Unit Hydrograph (HSS). hydrologic method. is located in Jati Village, Kedun...

rock has been advantageously employed in hydraulic structures such as rockfill dams, gabion weirs and drain works. one rockfill dam applications can be flood control in wa-tershed management. the objectives of building rockfill detention dams are flow storage for a specific period and lowering of the outflow hydrograph. as this type of dam consists of coarse particles, seepage flow will deviate...

Mobile Ad hoc Networks (MANETs) are wireless networks comprised of nodes which exhibit varying mobility and availability. Such networks are highly volatile, with network membership changing unpredictably over time. As Wifi-enabled mobile devices such as smartphones have become more ubiquitous and powerful, new applications which utilize ad hoc networking have emerged such as mobile multiplayer ...
