In wireless sensor networks, an important issue of Geographic Routing is “local minimum” problem, which is caused by “hole” that blocks the greedy forwarding process. Existing geographic routing algorithms use perimeter routing strategies to find a long detour path when such a situation occurs. To avoid the long detour path, recent research focuses on detecting the hole in advance, then the nod...
VANET have recently been the topic of extensive research due to its wide range of applications and unique characteristics. Routing is very important issue in VANET. Greedy forwarding is one of the most suitable solutions for routing in VANET. Due to its high mobility and frequent changing velocities of vehicles, greedy forwarding protocols are known to be more suitable and useful to VANET. In t...
Geographic information systems (GIS) are increasingly using geospatial data from the Web to produce geographic information. One big challenge is to find the relevant data, which often is based on keywords or even file names. However, these approaches lack semantics. Thus, it is necessary to provide mechanisms to prepare data to help retrieval of semantically relevant data. This paper proposes a...
Node Location information may reduce the overall communication overhead for packet forwarding in Mobile Ad-Hoc Networks (MANETs). This paper proposes a novel Geographic Location Aware Adaptive Routing (GLAAR) protocol to reduce the computation and communication requirement for selection of next node (hop) for packet forwarding. Proposed protocol fetches the node location information using GPS a...
Information integration and semantic heterogeneity are not trivial tasks. An integrated view must be able to describe various heterogeneous data sources and its interrelation to obtain shared conceptualizations. In this paper, we propose an approach to make a conceptualization of the real world based on conceptual schemas, which are used to generate a semantic description of the geospatial doma...
Multicasting is the transmission of packets to a group of zero or more hosts identified by a single destination address Multicasting is intended for group oriented computing. Typically the members of a host group are dynamic that is hosts may join and leave groups at any time T. In Mobile Ad hoc Networks communication among the groups is more important. To implement group communication we use e...
Geographic routing uses the physical locations of devices for routing purposes instead of the conventional routing protocols which make use of logical addressing schemes representing an abstract hierarchy. Greedy geographic routing is a popular method favoured for its efficiency and its simplicity that considers only one hop neighbours. Greedy routing needs only minimal network information and ...
