....multipath routing, whether deliberate or not, may be among them in today s or future networks. Many previous studies in fact treat these two causes separately. Mis ordering caused by packet retransmission is studied under the name of automatic repeat request (ARQ) protocol [17] 11] 13] 16] 1] [14] [15] It is typically assumed that ARQ is a link layer protocol between a sender receiver pair over a link with constant propagation delay. When the communication channel from the sender to the receiver is noisy, the sender needs to retransmit corrupted packets based on the feedback information ....

....is noisy, the sender needs to retransmit corrupted packets based on the feedback information it gets from the receiver. Researchers have mainly been concerned with the throughput of ARQ protocols. Several papers deal with the resequencing delay at the receiver caused by packet retransmissions [14] [15] Note that the end to end reliable transport protocols, such as TCP, resemble the link layer ARQ protocol in the areas of packet retransmission at the sender and resequencing at the receiver. In this paper, we borrow the term ARQ even though what we have is not the same as the link layer ....

....# sources The derivation of the resequencing buffer occupancy for # sources is similar to the two source case. Yet, the notion of the # # # (minimum valued packet) is helpful here. The # # # at time is the lowest indexed packet that has not arrived at the destination s receiver by time # (see [15]) For instance, if packets 1 through 15 arrived at the destination s receiver, but packet 16 did not, packet 16 is the # # # . From the definition of the # # # , for the model we consider it is easy to observe that: i) The resequencing buffer occupancy is exactly the number of packets indexed ....

....(which includes packets in the source and waiting buffers) E[q] q snae s : 26) 3 Resequencing Delay In this section, we give an approximate analysis of the mean resequencing delay under heavy traffic, i.e. packets are always supplied. This assumption has also been used in previous studies [8, 9], but for a static channel. We adapt the analytical approach in [8] which assumes i.i.d. packet error probabilities, to the underlying case where packet errors are correlated in a Markovian manner. Let X(t) 4 = X 1 (t) X 2 (t) Delta Delta Delta ; X s (t) denote the set of identifiers for ....

....the actual mean resequencing delay. Numerical results and simulations indicate that our approximate analysis is sufficiently accurate for a wide range of parameter values. 1 Introduction Automatic repeat request (ARQ) protocols are used to provide reliable data transfer in wireless communications [1, 9, 11]. In these protocols, the transmitter sends a packet that consists of payload bits and error detection code. The receiver checks the integrity of the packet by decoding the error detection code. Depending on the outcome of the decoder, a positive acknowledgment (ACK) or a negative acknowledgment ....
