| Abstract | In mobile ad hoc networks (MANETs), there are many applications in which mobile users share information by accessing data held by other users. Typical examples are collaborative rescue operations at a disaster site, military operations, and exchange of word-of-mouth information in a shopping mall. For such applications, preventing the deterioration of data availability at the point of network partitioning is a very significant issue. Data replication is the most promising solution to this problem [2, 5]. However, consistency management of data operations on replicas is generally very difficult in MANETs because of network partitioning. In our previous work, we have defined several consistency levels for MANET applications and designed protocols to achieve these consistency levels. These protocols are mainly based on a dynamic quorum system to cope with network partitioning and node and network failures [2]. In [3], we have further investigated the impact of quorum construction on the system performance through simulation studies. Specifically, we changed the number of mobile nodes that replicate data items and which nodes replicate each data item in the simulations and examined the impact on the system performance in terms of data availability and traffic. In this paper, we first briefly present our recent work published in [3]. Then, we discuss future directions for adaptive quorum construction for consistency management. |
