Abstract: This paper presents priority-first packet scheduling
approach for heterogeneous traffic flows in low data rate heterogeneous wireless sensor networks (HWSNs).
A Scheduling in Wireless Sensor Networks is called as the packet scheduling
, which is used for managing the sequencing of packets in wireless sensor network of the transmitting and receiving queues, which uses circular data buffer.
The traditional packet scheduling
algorithm used in most systems is First-In-First-Out (FIFO), which places all packets into a single queue and processes them in the same order in which they are received.
The required link capacity would depend on different flows packet scheduling
and queue management at core routers.
In order to avoid the shortcomings of multi-path transmission, some packet scheduling
algorithms have been proposed.
Such assignment of PRB based on the quality of channels is called frequency-domain packet scheduling
Thus, a good packet scheduling
scheme that copes with both service classes simultaneously, delivers balanced QoS and utilizes the system radio resources efficiently is the solution to this.
Emergence growth in high-speed packet switch network initiates the need of packet scheduling
These high data rates have become possible as a result of inclusion of new technologies such as Link Adaptation Hybrid Automatic Repeat Request (HARQ) Retransmissions and Fast Packet Scheduling
There are some scheduling algorithms to support packet scheduling
in wire and wireless networks.
Among their topics are mobility challenges and management in the future wireless heterogeneous networks, heterogeneous meshed wireless back-haul network integrating uni-directional technologies, an intelligent fuzzy quality-of-service model in wireless ad hoc networks, packet scheduling
in home and business femtocell networks, and adaptive coexistence between cognitive and fiber networks.
The solution features hardware mechanisms that cancel out board- and chip-level RF interference at the source to simplify design process, while enhanced WiFi/Bluetooth/Bluetooth Low Energy inter-core communication prioritises packet scheduling
and supports more connections in parallel.
