摘要：The huge, s uccessive and rapid advancement in technology in recent years played a major role in peoples' everyday activities. GPS-enabled devices have become ub iquitous and location-based services (LBS) are equally so. The LBS is considered among the prominent application for Mobile Ad hoc Network (MANET). In fact, observation of a node to issue K Nearest Neighbor (K-NN) q ueries is commonly found in the location-based services. Although among wireless researchers, MANET is gaining momentum because of its significant advantages. However MANET has some limitation that is the key challenging in designing system protocols such as limitations on network bandwidth, resource consuming problem and mobility. Among all these limitations, mobility has the most significant effect on routing protocol performance . Mobility of nodes is categorized into entity based or group based. In entity mobility each node moves irrespective of each other. Group mobility has shown that nodes of the same group move in a similar moving behavior. As such, several mob ile ad hoc networks applications are based on group mobility. However existing solution for K-NNs queries is based on single node's mobility. Recently Group mobility has been utilized to improve performance and increase scalability routing. Moreover, deployment of several access points in the ad hoc network resulted in the enhancement of the connectivity. Thus, to overcome the aforementioned limitations, this paper is proposing a novel method, namely Group Based K-NN Queries with wireless integration (GB-KNN-WI). The proposed method is to process a K-NN query in MANETs by combining group mobility based model with wireless integration to enhance the connectivity and resource consuming. I n this method, MANET is divided into groups. And the groups are then treated as a single node, thus, resulting in the exchange of K -NN query between groups rather than single nodes. Thus, avoiding the problem that arises from the resource-consuming of nodes, and will speed up the packet delivery. Each group has a leader that is a central point in a group and responsible for communication with other group. Hybrid routing protocols are utilized. In order to increase the connectivity, the group leader has the ability to connect to wireless infrastructure in case that there is no connectivity with other groups. According to the comparison and contrast of previous work related to group mobility and integration networks the proposed method is a promising solution to mobility limitations in MANET.
