Abstract- In this paper we show the comparative study of route reservation techniques in ad hoc wireless networks. The reservation technique falls into two groups’ reservation-based (RB) communication and non-reservation-based (NRB) communication. In an NRB scheme, an intermediate node can simultaneously serve as relay for more than one source while RB scheme reserves intermediate nodes before the actual transmission begins. The paper describes the Analytical comparison for evaluating the performance, in terms of delay, good put, and throughput of RB and NRB schemes.
Keywords- ad hoc wireless networks, resource reservation, performance analysis, good put, throughput, delay.
I. INTRODUCTION There are two switching techniques used in wired networks- circuit switching and packet switching [1]. The major difference between them is the way resources are shared. Circuit switching provides exclusive access to the resources by means of reservation on the other hand resources are shared on demand, without prior reservation in packet switching. The packet switching is suitable for a wired data network such as the Internet; it is not clear whether this is true in the case of ad hoc wireless networks. In this paper, we compare the two switching paradigms: reservation-based (RB) and non-reservation-based (NRB) switching for ad hoc wireless network. The concepts of reservation and non-reservation are analogous to those of circuit switching and packet switching in wired networks, respectively.
* In an NRB scheme, an intermediate node can simultaneously serve as relay for more than one source. Hence, the resources (in terms of relaying nodes) are shared in an on-demand fashion. This is typical for most of the routing protocols for wireless ad hoc networks proposed in the literature [2].
