+# Enhanced Multi-Agent Communication and Hierarchical Cooperation - Implementation Summary
+
+## Overview
+
+This document summarizes the comprehensive improvements made to the multi-agent communication system, message frequency management, and hierarchical cooperation in the swarms framework. The enhancements focus on reliability, performance, and advanced coordination patterns.
+
+## 🚀 Key Improvements Implemented
+
+### 1. Enhanced Communication Infrastructure
+
+#### **Reliable Message Passing System**
+- **Message Broker**: Central message routing with guaranteed delivery
+- **Priority Queues**: Task prioritization (LOW, NORMAL, HIGH, URGENT, CRITICAL)
+- **Retry Mechanisms**: Exponential backoff for failed message delivery
+- **Message Persistence**: Reliable storage and recovery of messages
+- **Acknowledgment System**: Delivery confirmation and tracking
+
+#### **Rate Limiting and Frequency Management**
