RLC Effects on Throughput in a Mobile System
نویسنده
چکیده
Today wireless data communication is growing rapidly. In particular, multimedia and Internet communication by wireless systems are the most popular services. Also, the architecture of wireless networks is varying to provide such services better. In this paper, we review UTRAN (UMTS Terrestrial Radio Access Network) focusing on the RLC (Radio Link Control) sub-layer, its error recovery mechanisms and transport channels when connected to Internet. Besides, we consider data flows based on the acknowledgement mode RLC, the transparent mode MAC and simulate the effects of RLC protocol and erroneous MAC PDUs and delays, on the throughput. Finally, we evaluate the throughput versus MAC PDU retransmission times as well as the throughput efficiency versus MAC PDU retransmission times and data block lengths.

متن کاملDynamic Control of RLC Buffer Size for Latency Minimization in Mobile RAN
5G is expected to expand the set of interactive applications enabled by the mobile network. Low end-to-end packet latency is a fundamental requirement for proper operation of those applications, but may be compromised in packet buffers shared with elastic applications that use greedy TCP sources for end-to-end transport. The accumulation of queuing delay by the elastic application degrades the ...
متن کاملA New Intrusion Detection System to deal with Black Hole Attacks in Mobile Ad Hoc Networks
By extending wireless networks and because of their different nature, some attacks appear in these networks which did not exist in wired networks. Security is a serious challenge for actual implementation in wireless networks. Due to lack of the fixed infrastructure and also because of security holes in routing protocols in mobile ad hoc networks, these networks are not protected against attack...
