Distributed termination detection in a mobile wireless network
Abstract- In a mobile wireless network, restrictions exist which demand creative solutions to classical distributed prob-lems. Distributed termination detection, the problem of de-ciding when the whole of a distributed computation has com-pleted, is one such distributed problem. In this paper, an existing message optimal distributed termination detection algorithm is selected and modified to enhance its behavior in a mobile wireless network; the modifications entail reduc-ing the number of messages received and transmitted by the mobile nodes involved in the distributed computation.
A taxonomy of distributed termination detection algorithms
An important problem in the field of distributed systems is that of detecting the termination of a distributed computation. Distributed termination detection (DTD) is a di cult problem due to the fact that there is no simple way of gaining knowledge of the global state of the system. Of the algorithms proposed in the last 15 years, there are many similarities. We have categorized these algorithms based on the following factors: algorithm type (e.g., wave, credit-recovery), required network topology, algorithm symmetry, required process knowledge, communication protocol (synchronous or asynchronous), communication channel behavior (first-in first-out (FIFO) or non-FIFO), message optimality, and fault tolerance. This methodology is intended to guide future research in DTD algorithms (since research continues on these algorithms) as well as to provide a classification survey for thi
