“…There are 3 types of routing protocols namely, proactive, reactive, and hybrid as shown in Figure 1 [Ghosh, T, Tiwari, S & Sahay, J 2017]. Two routing protocols AODV, and OLSR were analyzed for this paper, as they are the best for VoIP as shown in many studies [Hassine, K & Frikha, M 2017] [Jin, C, Wei, DX & Low, SH 2006]. Hoc On-Demand Distance Vector (AODV) is a reactive routing protocol, it uses broadcast discovery mechanism and sequence number to find the best fresh recent routes to the destination.…”

“…It starts his discovery phase when a node needs to transmit data to another node, and record his routes in its routing table until the source node finishes transmitting, then the routes will be deleted, and start new path discovery again when needed. Therefore, it causes lower overhead and more delays during transmission [Hassine, K & Frikha, M 2017]. While Optimized Link State Routing (OLSR) is a proactive routing protocol, it uses a group of selected nodes called Multipoint Relays "MPR's to exchange their recent routing information between them, giving a speed to route discovery phase.…”

Voice over internet protocol (VoIP) calls are increasingly transported over computer-based networking due to several factors, such as low call rates. However, point-to-point (P-P) calls, as a division of VoIP, are encountering a capacity utilization issue. The main reason for that is the giant packet header, especially when compared to the runt P-P calls packet payload. Therefore, this research article introduced a method to solve the liability of the giant packet header of the P-P calls. The introduced method is named voice segment compaction (VSC). The VSC method employs the unneeded P-P calls packet header elements to carry the voice packet payload. This, in turn, reduces the size of the voice payload and improves network capacity utilization. The preliminary results demonstrated the importance of the introduced VSC method, while network capacity improved by up to 38.33%.

“…Therefore, the ratio of the consumed bandwidth by the header is between 66.7% and 85.71%, based on the length of the digital speech sample. The bandwidth consumed by the large header can be lightened by assembling several PDUs of the transport layer (Speech sample + RTP + UDP) in one IPv6 header, known as packet multiplexing [5,7]. The resulted packet is called multiplexed packet (P-Mux).…”

The demand for the telecommunication services, such as IP telephony, has increased dramatically during the COVID-19 pandemic lockdown. IP telephony should be enhanced to provide the expected quality. One of the issues that should be investigated in IP telephony is bandwidth utilization. IP telephony produces very small speech samples attached to a large packet header. The header of the IP telephony consumes a considerable share of the bandwidth allotted to the IP telephony. This wastes the network's bandwidth and influences the IP telephony quality. This paper proposes a mechanism (called Smallerize) that reduces the bandwidth consumed by both the speech sample and the header. This is achieved by assembling numerous IP telephony packets in one header and use the header's fields to carry the speech sample. Several metrics have been used to measure the achievement Smallerize mechanism. The number of calls has been increased by 245.1% compared to the typical mechanism. The bandwidth saving has also reached 68% with the G.28 codec. Therefore, Smallerize is a possible mechanism to enhance bandwidth utilization of the IP telephony.
