In order to solve the rbuf blocking in concurrent multipath transfer, firstly, this paper analyzes the reason for receiving buffer blocking and the disadvantages of traditional retransmission policies. And then, it proposes an improved retransmission policy — RTX-CR (retransmission-congestion window and RTT), which can reduce rbuf blocking. The simulation indicates that the retransmission policy can...
Delay Tolerant Mobile Sensor Networks (DTMSN) has the enormous potential to expand its applications in many previously impossible fields. Because of its intermittent link and limited network resources, this network needs an effective data forwarding algorithm to ensure valid data forwarding and highly delivery ratio. Recent approaches have drawbacks of computing nodes' delivery probability, because...
Femtocells, also called home base stations, are small cellular access points installed by home users to get better indoor voice and data coverage with lower network operation cost. Considering the coexistence of eNB (macro cell) and a huge number of Home eNBs (femto cells), the assignment of Physical Cell Identity (PCI) among the different cells would be quite complex, especially in the user-deployment...
Femto cells, also called home base stations, are small cellular access points installed by home users to get better indoor voice and data coverage with lower network operation cost. In this paper, the deployments of femto cells within LTE cellular networks are investigated. Based on the current partial co-channel deployment configuration for LTE Home evolved NodeB, a novel scheme of femtocell-aware...
Research on multi-channel MAC has been got much attention in wireless networks. Extensions of NS2 mobile node architecture (MNA) to support multi-channel MAC simulation are not adaptable to home gateway configurations. This paper proposes a versatile model architecture (VMA) to make simulation of home gateway available. Based on the previous works, VMA defines an entity of data link adaptor and is...
