Efficient Multi-way Tree Search Algorithm for Huffman Decoder

Ternary Tree and Memory-Efficient Huffman Decoding Algorithm

In this study, the focus was on the use of ternary tree over binary tree. Here, a new one pass Algorithm for Decoding adaptive Huffman ternary tree codes was implemented. To reduce the memory size and fasten the process of searching for a symbol in a Huffman tree, we exploited the property of the encoded symbols and proposed a memory efficient data structure to represent the codeword length of ...

A fast algorithm for Huffman decoding based on a recursion Huffman tree

A Work Efficient Parallel Algorithm for Constructing Huffman Codes

Given an tilphabet C = (al! . . . , a,) and a corresponding list of weights [WI, . . . , w,], a Huffman code for this alphabet is a prefix code that minimizes the weighted length of a code string, defined to be Cr.., wili, where li is the length of the code assigned to ai. A. Huffman code can be generated in O(n log n) time for an unsorted list of weights alld in Cl(n) time if the weights are a...

A Novel Multicast Tree Construction Algorithm for Multi-Radio Multi-Channel Wireless Mesh Networks

Many appealing multicast services such as on-demand TV, teleconference, online games and etc. can benefit from high available bandwidth in multi-radio multi-channel wireless mesh networks. When multiple simultaneous transmissions use a similar channel to transmit data packets, network performance degrades to a large extant. Designing a good multicast tree to route data packets could enhance the...

ITS: An Efficient Limited-Memory Heuristic Tree Search Algorithm

This paper describes a new admissible tree search algorithm called Iterative Threshold Search (ITS). ITS can be viewed as a much-simpliied version of MA* 1], and a generalized version of MREC 12]. We also present the following results: 1. Every node generated by ITS is also generated by IDA*, even if ITS is given no more memory than IDA*. In addition, there are trees on which ITS generates O(N)...
