In contrast, if RLNC is applied, all data packets are decoded after the second transmission, yielding an APDD of 2. Table 1 A example of packet reception state p 1 p 2 p 3 p 4 R 1 wants wants has has R 2 has has wants wants.
Upon reception of P i′, i ∈ [1,n], l i source packets can be decoded.
Figure 6 ACN warning average Packet Reception Rate, p SB for repetition codes and raptor codes.
Finally, the ACN warning packet reception rate (p SB) for different vehicle densities and antenna schemes is analysed.
It is seen in Figure 6 that high traffic density has the worst packet reception rate p SB performance.
Figure 15 presents the enhance percentage of reliability for the whole network in different link qualities when employing URL scheme under the condition that guarantee the same lifetime and the end-to-end packet reception rate p e ≥ 70%%.
(a) Average end-to-end delay τ SB, (b) packet reception rate p SBwith maximum latency of 50 ms. In this article we have investigated the latency and reliability performance of a V2V communication system using raptor codes and compared them to repetition codes as proposed by the WAVE standard.
Furthermore, if the PPM condition holds (viz., upon reception of p, (n_i) generates a random number r, and r is less than a preset empirical value v), (n_i) will add its ID to the provenance of p. If p has not been marked by the contacts of (n_i), (n_i) will add its ID to the provenance of p and then send it to the next node.
The downlink circuit power for transmission and reception are respectively p c =50 W and p c =42 W. The energy consumption in uplink is the energy consumed by the circuit power ({p^{u}_{c}}) and transmit power p u in the N s feedback slots at each user.
The reception time of P and B are T i AP and T i AB, respectively.
That is why the initial PPP density has little effect on the final probability of successful reception when λ p tends to infinity.
