In recent years, wireless sensor networks are widely used in various applications. This paper proposes a data gathering protocol with mobile relays to solve the partition problem of sensor network. When some sensor nodes have exhausted their batteries or are failure, some holes occur in the network topology. Because of the existence and enlargement of the holes, the sensor network is partitioned into...
Service discovery is a crucial operation for the usability of mobile ad hoc networks (MANETs). Traditional solutions to service discovery that were adopted on the Internet are not well suited for MANETs because of their dynamic nature. This paper presents a novel service discovery protocol based on a hierarchical grid architecture in an ad hoc network. The geographical area of a MANET is divided into...
Wireless communications and digital electronics have enabled the development of low-power, low-cost, multifunctional sensors. The functionality of sensor network mainly is the measurement collection. The previous proposed protocols mainly focus on broadcasting tree structure, but it may not be efficient in data gathering. In this paper, we propose novel tree architecture that is a dynamic, adjustable,...
